|Summary: Secure Shell Client and Server (Remote Login Program)
SSH (Secure Shell) is a program for logging into and executing commands on a remote machine. It is intended to replace rsh (rlogin and rsh) and provides openssl (secure encrypted communication) between two untrusted hosts over an insecure network. xorg-x11 (X Window System) connections and arbitrary TCP/IP ports can also be forwarded over the secure channel.
BSD-2-Clause AND MIT
* Mon Nov 02 2020 Hans Petter Jansson <firstname.lastname@example.com> - Add openssh-fips-ensure-approved-moduli.patch (bsc#1177939). This ensures only approved DH parameters are used in FIPS mode. * Fri Sep 25 2020 Hans Petter Jansson <firstname.lastname@example.com> - Add openssh-8.1p1-ed25519-use-openssl-rng.patch (bsc#1173799). This uses OpenSSL's RAND_bytes() directly instead of the internal ChaCha20-based implementation to obtain random bytes for Ed25519 curve computations. This is required for FIPS compliance. * Fri Feb 28 2020 Ludwig Nussel <firstname.lastname@example.com> - Don't recommend xauth to avoid pulling in X. * Tue Feb 18 2020 Fabian Vogt <firstname.lastname@example.com> - Add patches to fix the sandbox blocking glibc on 32bit platforms (boo#1164061): * openssh-8.1p1-seccomp-clock_nanosleep_time64.patch * openssh-8.1p1-seccomp-clock_gettime64.patch * Tue Feb 11 2020 Hans Petter Jansson <firstname.lastname@example.com> - Add openssh-8.1p1-use-openssl-kdf.patch (jsc#SLE-9443). This performs key derivation using OpenSSL's SSHKDF facility, which allows OpenSSH to benefit from the former's FIPS certification status. * Thu Nov 21 2019 Hans Petter Jansson <firstname.lastname@example.com> - Make sure ssh-keygen runs if SSHD_AUTO_KEYGEN variable is unset or contains an unrecognized value (bsc#1157176). * Fri Nov 08 2019 Cristian Rodríguez <email@example.com> - Add openssh-8.1p1-seccomp-clock_nanosleep.patch, allow clock_nanosleep glibc master implements multiple functions using that syscall making the privsep sandbox kill the preauth process. * Thu Oct 17 2019 Hans Petter Jansson <firstname.lastname@example.com> - Update openssh-7.7p1-audit.patch to fix crash (bsc#1152730). Fix by Enzo Matsumiya (firstname.lastname@example.com). This was integrated in a separate code stream merged with the Oct. 10 update; the patch was also rebased and renamed to openssh-8.1p1-audit.patch. * Mon Oct 14 2019 Hans Petter Jansson <firstname.lastname@example.com> - Add openssh-7.9p1-keygen-preserve-perms.patch (bsc#1150574). This attempts to preserve the permissions of any existing known_hosts file when modified by ssh-keygen (for instance, with -R). - Added openssh-7.9p1-revert-new-qos-defaults.patch, which reverts an upstream commit that caused compatibility issues with other software (bsc#1136402). * Mon Oct 14 2019 Hans Petter Jansson <email@example.com> - Run 'ssh-keygen -A' on startup only if SSHD_AUTO_KEYGEN="yes" in /etc/sysconfig/ssh. This is set to "yes" by default, but can be changed by the system administrator (bsc#1139089). * Mon Oct 14 2019 Hans Petter Jansson <firstname.lastname@example.com> - Add openssh-7.9p1-keygen-preserve-perms.patch (bsc#1150574). This attempts to preserve the permissions of any existing known_hosts file when modified by ssh-keygen (for instance, with -R). * Thu Oct 10 2019 Hans Petter Jansson <email@example.com> - Version update to 8.1p1: * ssh-keygen(1): when acting as a CA and signing certificates with an RSA key, default to using the rsa-sha2-512 signature algorithm. Certificates signed by RSA keys will therefore be incompatible with OpenSSH versions prior to 7.2 unless the default is overridden (using "ssh-keygen -t ssh-rsa -s ..."). * ssh(1): Allow %n to be expanded in ProxyCommand strings * ssh(1), sshd(8): Allow prepending a list of algorithms to the default set by starting the list with the '^' character, E.g. "HostKeyAlgorithms ^ssh-ed25519" * ssh-keygen(1): add an experimental lightweight signature and verification ability. Signatures may be made using regular ssh keys held on disk or stored in a ssh-agent and verified against an authorized_keys-like list of allowed keys. Signatures embed a namespace that prevents confusion and attacks between different usage domains (e.g. files vs email). * ssh-keygen(1): print key comment when extracting public key from a private key. * ssh-keygen(1): accept the verbose flag when searching for host keys in known hosts (i.e. "ssh-keygen -vF host") to print the matching host's random-art signature too. * All: support PKCS8 as an optional format for storage of private keys to disk. The OpenSSH native key format remains the default, but PKCS8 is a superior format to PEM if interoperability with non-OpenSSH software is required, as it may use a less insecure key derivation function than PEM's. - Additional changes from 8.0p1 release: * scp(1): Add "-T" flag to disable client-side filtering of server file list. * sshd(8): Remove support for obsolete "host/port" syntax. * ssh(1), ssh-agent(1), ssh-add(1): Add support for ECDSA keys in PKCS#11 tokens. * ssh(1), sshd(8): Add experimental quantum-computing resistant key exchange method, based on a combination of Streamlined NTRU Prime 4591^761 and X25519. * ssh-keygen(1): Increase the default RSA key size to 3072 bits, following NIST Special Publication 800-57's guidance for a 128-bit equivalent symmetric security level. * ssh(1): Allow "PKCS11Provider=none" to override later instances of the PKCS11Provider directive in ssh_config, * sshd(8): Add a log message for situations where a connection is dropped for attempting to run a command but a sshd_config ForceCommand=internal-sftp restriction is in effect. * ssh(1): When prompting whether to record a new host key, accept the key fingerprint as a synonym for "yes". This allows the user to paste a fingerprint obtained out of band at the prompt and have the client do the comparison for you. * ssh-keygen(1): When signing multiple certificates on a single command-line invocation, allow automatically incrementing the certificate serial number. * scp(1), sftp(1): Accept -J option as an alias to ProxyJump on the scp and sftp command-lines. * ssh-agent(1), ssh-pkcs11-helper(8), ssh-add(1): Accept "-v" command-line flags to increase the verbosity of output; pass verbose flags though to subprocesses, such as ssh-pkcs11-helper started from ssh-agent. * ssh-add(1): Add a "-T" option to allowing testing whether keys in an agent are usable by performing a signature and a verification. * sftp-server(8): Add a "email@example.com" protocol extension that replicates the functionality of the existing SSH2_FXP_SETSTAT operation but does not follow symlinks. * sftp(1): Add "-h" flag to chown/chgrp/chmod commands to request they do not follow symlinks. * sshd(8): Expose $SSH_CONNECTION in the PAM environment. This makes the connection 4-tuple available to PAM modules that wish to use it in decision-making. * sshd(8): Add a ssh_config "Match final" predicate Matches in same pass as "Match canonical" but doesn't require hostname canonicalisation be enabled. * sftp(1): Support a prefix of '@' to suppress echo of sftp batch commands. * ssh-keygen(1): When printing certificate contents using "ssh-keygen -Lf /path/certificate", include the algorithm that the CA used to sign the cert. - Rebased patches: * openssh-7.7p1-IPv6_X_forwarding.patch * openssh-7.7p1-X_forward_with_disabled_ipv6.patch * openssh-7.7p1-cavstest-ctr.patch * openssh-7.7p1-cavstest-kdf.patch * openssh-7.7p1-disable_openssl_abi_check.patch * openssh-7.7p1-fips.patch * openssh-7.7p1-fips_checks.patch * openssh-7.7p1-hostname_changes_when_forwarding_X.patch * openssh-7.7p1-ldap.patch * openssh-7.7p1-seed-prng.patch * openssh-7.7p1-sftp_force_permissions.patch * openssh-7.7p1-sftp_print_diagnostic_messages.patch * openssh-8.0p1-gssapi-keyex.patch (formerly openssh-7.7p1-gssapi_key_exchange.patch) * openssh-8.1p1-audit.patch (formerly openssh-7.7p1-audit.patch) - Removed patches (integrated upstream): * 0001-upstream-Fix-two-race-conditions-in-sshd-relating-to.patch * openssh-7.7p1-seccomp_ioctl_s390_EP11.patch * openssh-7.9p1-CVE-2018-20685.patch * openssh-7.9p1-brace-expansion.patch * openssh-CVE-2019-6109-force-progressmeter-update.patch * openssh-CVE-2019-6109-sanitize-scp-filenames.patch * openssh-CVE-2019-6111-scp-client-wildcard.patch - Removed patches (obsolete): * openssh-openssl-1_0_0-compatibility.patch * Mon Aug 19 2019 email@example.com - don't install SuSEfirewall2 service on Factory, since SuSEfirewall2 has been replaced by firewalld, see [1]. [1]: https://lists.opensuse.org/opensuse-factory/2019-01/msg00490.html * Mon Jul 22 2019 Fabian Vogt <email@example.com> - ssh-askpass: Try a fallback if the other option is not available * Fri May 31 2019 Vítězslav Čížek <firstname.lastname@example.com> - Fix a crash with GSSAPI key exchange (bsc#1136104) * modify openssh-7.7p1-gssapi_key_exchange.patch * Thu Mar 28 2019 Vítězslav Čížek <firstname.lastname@example.com> - Fix a double free() in the KDF CAVS testing tool (bsc#1065237) * modify openssh-7.7p1-cavstest-kdf.patch * Tue Mar 12 2019 Vítězslav Čížek <firstname.lastname@example.com> - Minor clean-up of the fips patches, modified openssh-7.7p1-fips.patch openssh-7.7p1-fips_checks.patch * Mon Mar 11 2019 Vítězslav Čížek <email@example.com> - Fix two race conditions in sshd relating to SIGHUP (bsc#1119183) * 0001-upstream-Fix-two-race-conditions-in-sshd-relating-to.patch * Thu Feb 28 2019 Vítězslav Čížek <firstname.lastname@example.com> - Correctly filter out non-compliant algorithms when in FIPS mode (bsc#1126397) * A hunk was applied to a wrong place due to a patch fuzz when the fips patch was being ported to openssh 7.9p1 - update openssh-7.7p1-fips.patch * Wed Feb 27 2019 Vítězslav Čížek <email@example.com> - Remove the "KexDHMin" config keyword (bsc#1127180) It used to allow lowering of the minimal allowed DH group size, which was increased to 2048 by upstream in the light of the Logjam attack. The code was broken since the upgrade to 7.6p1, but nobody noticed. As apparently no one needs the functionality any more, let's drop the patch. It's still possible to use the fixed 1024-bit diffie-hellman-group1-sha1 key exchange method when working with legacy systems. - drop openssh-7.7p1-disable_short_DH_parameters.patch - updated patches: openssh-7.7p1-fips.patch openssh-7.7p1-fips_checks.patch openssh-7.7p1-gssapi_key_exchange.patch * Mon Feb 18 2019 Pedro Monreal Gonzalez <email@example.com> - Handle brace expansion in scp when checking that filenames sent by the server side match what the client requested [bsc#1125687] * openssh-7.9p1-brace-expansion.patch * Thu Feb 14 2019 Pedro Monreal Gonzalez <email@example.com> - Updated security fixes: * [bsc#1121816, CVE-2019-6109] Sanitize scp filenames via snmprintf and have progressmeter force an update at the beginning and end of each transfer. Added patches: - openssh-CVE-2019-6109-sanitize-scp-filenames.patch - openssh-CVE-2019-6109-force-progressmeter-update.patch * [bsc#1121821, CVE-2019-6111] Check in scp client that filenames sent during remote->local directory copies satisfy the wildcard specified by the user. Added patch: - openssh-CVE-2019-6111-scp-client-wildcard.patch * Removed openssh-7.9p1-scp-name-validator.patch * Thu Feb 14 2019 Tomáš Chvátal <firstname.lastname@example.com> - Change the askpass wrapper to not use x11 interface: * by default we use the -gnome UI (which is gtk3 only, no gnome dep) * if desktop is KDE/LxQt we use ksshaskpass * Mon Jan 28 2019 Pedro Monreal Gonzalez <firstname.lastname@example.com> - Remove old conditionals * Fri Jan 25 2019 Pedro Monreal Gonzalez <firstname.lastname@example.com> - Move ssh-ldap* man pages into openssh-helpers [bsc#1051531] * Thu Jan 24 2019 Pedro Monreal Gonzalez <email@example.com> - Allow root login by default [bsc#1118114, bsc#1121196] * Added/updated previous patch openssh-7.7p1-allow_root_password_login.patch * Mention the change in README.SUSE * Thu Jan 24 2019 Pedro Monreal Gonzalez <firstname.lastname@example.com> - Added SLE conditionals in the spec files: * Keep gtk2-devel in openssh-askpass-gnome in SLE * Keep krb5-mini-devel in SLE - Removed obsolete configure options: * SSH protocol 1 --with-ssh1 * Smart card --with-opensc - Cleaned spec file with spec-cleaner * Wed Jan 16 2019 Pedro Monreal Gonzalez <email@example.com> - Security fix: * [bsc#1121816, CVE-2019-6109] scp client spoofing via object name * [bsc#1121818, CVE-2019-6110] scp client spoofing via stderr * [bsc#1121821, CVE-2019-6111] scp client missing received object name validation * Added patch openssh-7.9p1-scp-name-validator.patch * Fri Jan 11 2019 Pedro Monreal Gonzalez <firstname.lastname@example.com> - Security fix: [bsc#1121571, CVE-2018-20685] * The scp client allows remote SSH servers to bypass intended access restrictions * Added patch openssh-7.9p1-CVE-2018-20685.patch * Thu Jan 03 2019 Pedro Monreal Gonzalez <email@example.com> - Added compatibility with SuSEfirewall2 [bsc#1118044] * Tue Dec 11 2018 Pedro Monreal Gonzalez <email@example.com> - Update the firewall rules in Tumbleweed * Mon Nov 26 2018 Vítězslav Čížek <email@example.com> - Fix build with openssl < 1.1.0 * add openssh-openssl-1_0_0-compatibility.patch * Wed Oct 31 2018 Cristian Rodríguez <firstname.lastname@example.com> - openssh-7.7p1-audit.patch: fix sshd fatal error in mm_answer_keyverify: buffer error: incomplete message [bnc#1114008] * Mon Oct 22 2018 Pedro Monreal Gonzalez <firstname.lastname@example.com> - Version update to 7.9p1 * ssh(1), sshd(8): the setting of the new CASignatureAlgorithms option (see below) bans the use of DSA keys as certificate authorities. * sshd(8): the authentication success/failure log message has changed format slightly. It now includes the certificate fingerprint (previously it included only key ID and CA key fingerprint). * ssh(1), sshd(8): allow most port numbers to be specified using service names from getservbyname(3) (typically /etc/services). * sshd(8): support signalling sessions via the SSH protocol. A limited subset of signals is supported and only for login or command sessions (i.e. not subsystems) that were not subject to a forced command via authorized_keys or sshd_config. bz#1424 * ssh(1): support "ssh -Q sig" to list supported signature options. Also "ssh -Q help" to show the full set of supported queries. * ssh(1), sshd(8): add a CASignatureAlgorithms option for the client and server configs to allow control over which signature formats are allowed for CAs to sign certificates. For example, this allows banning CAs that sign certificates using the RSA-SHA1 signature algorithm. * sshd(8), ssh-keygen(1): allow key revocation lists (KRLs) to revoke keys specified by SHA256 hash. * ssh-keygen(1): allow creation of key revocation lists directly from base64-encoded SHA256 fingerprints. This supports revoking keys using only the information contained in sshd(8) authentication log messages. - Removed obsolete configuration option --with-tcp-wrappers, and - -with-opensc for s390 and s390x. - Removed patch merged upstream * openssh-7.7p1-openssl_1.1.0.patch - Refreshed patches * openssh-7.7p1-audit.patch * openssh-7.7p1-disable_short_DH_parameters.patch * openssh-7.7p1-fips.patch * openssh-7.7p1-gssapi_key_exchange.patch * openssh-7.7p1-seccomp_ipc_flock.patch * openssh-7.7p1-cavstest-ctr.patch * openssh-7.7p1-ldap.patch * Fri Oct 19 2018 Tomáš Chvátal <firstname.lastname@example.com> - Mention upstream bugs on multiple local patches - Adjust service to not spam restart and reload only on fails * Fri Oct 19 2018 Tomáš Chvátal <email@example.com> - Update openssh-7.7p1-sftp_force_permissions.patch from the upstream bug, and mention the bug in the spec * Fri Oct 19 2018 Tomáš Chvátal <email@example.com> - Drop patch openssh-7.7p1-allow_root_password_login.patch * There is no reason to set less secure default value, if users need the behaviour they can still set it up themselves - Drop patch openssh-7.7p1-blocksigalrm.patch * We had a bug way in past about this but it was never reproduced or even confirmed in the ticket, thus rather drop the patch * Wed Oct 17 2018 Tomáš Chvátal <firstname.lastname@example.com> - Disable ssh1 protocol support as neither RH or Debian enable this protocol by default anymore either. * Wed Oct 17 2018 Tomáš Chvátal <email@example.com> - Remove the mention of the SLE12 in the README.SUSE - Install firewall rules only when really needed (<SLE15) * Tue Oct 09 2018 Tomáš Chvátal <firstname.lastname@example.com> - Version update to 7.8p1: * For most details see release notes file * ssh-keygen(1): write OpenSSH format private keys by default instead of using OpenSSL's PEM format - Rebase patches to apply on 7.8p1 release: * openssh-7.7p1-fips.patch * openssh-7.7p1-cavstest-kdf.patch * openssh-7.7p1-fips_checks.patch * openssh-7.7p1-gssapi_key_exchange.patch * openssh-7.7p1-audit.patch * openssh-7.7p1-openssl_1.1.0.patch * openssh-7.7p1-ldap.patch * openssh-7.7p1-IPv6_X_forwarding.patch * openssh-7.7p1-sftp_print_diagnostic_messages.patch * openssh-7.7p1-disable_short_DH_parameters.patch * openssh-7.7p1-hostname_changes_when_forwarding_X.patch * openssh-7.7p1-pam_check_locks.patch * openssh-7.7p1-seed-prng.patch * openssh-7.7p1-systemd-notify.patch * openssh-7.7p1-X11_trusted_forwarding.patch - Dropped patches: * openssh-7.7p1-lastlog.patch * openssh-7.7p1-blocksigalrm.patch - Do not use env in script cavs_driver-ssh.pl - Added pam_keyinit to pam configuration file [bsc#1081947] * Tue Oct 09 2018 Tomáš Chvátal <firstname.lastname@example.com> - Format with spec-cleaner - Reduce conditionals to support SLE12+ only - Split out bundled patches to be normal patches applied over the package (use -p1 for patches): * openssh-7.7p1-allow_root_password_login.patch * openssh-7.7p1-X11_trusted_forwarding.patch * openssh-7.7p1-lastlog.patch * openssh-7.7p1-enable_PAM_by_default.patch * openssh-7.7p1-eal3.patch * openssh-7.7p1-blocksigalrm.patch * openssh-7.7p1-send_locale.patch * openssh-7.7p1-hostname_changes_when_forwarding_X.patch * openssh-7.7p1-remove_xauth_cookies_on_exit.patch * openssh-7.7p1-pts_names_formatting.patch * openssh-7.7p1-pam_check_locks.patch * openssh-7.7p1-disable_short_DH_parameters.patch * openssh-7.7p1-seccomp_getuid.patch * openssh-7.7p1-seccomp_geteuid.patch * openssh-7.7p1-seccomp_stat.patch * openssh-7.7p1-seccomp_ipc_flock.patch * openssh-7.7p1-seccomp_ioctl_s390_EP11.patch * openssh-7.7p1-fips.patch * openssh-7.7p1-cavstest-ctr.patch * openssh-7.7p1-cavstest-kdf.patch * openssh-7.7p1-fips_checks.patch * openssh-7.7p1-seed-prng.patch * openssh-7.7p1-systemd-notify.patch * openssh-7.7p1-gssapi_key_exchange.patch * openssh-7.7p1-audit.patch * openssh-7.7p1-openssl_1.1.0.patch * openssh-7.7p1-disable_openssl_abi_check.patch * openssh-7.7p1-no_fork-no_pid_file.patch * openssh-7.7p1-host_ident.patch * openssh-7.7p1-sftp_force_permissions.patch * openssh-7.7p1-X_forward_with_disabled_ipv6.patch * openssh-7.7p1-ldap.patch * openssh-7.7p1-IPv6_X_forwarding.patch * openssh-7.7p1-sftp_print_diagnostic_messages.patch * Tue Sep 18 2018 firstname.lastname@example.com - seccomp_filter sandbox is not supported on ppc * Mon Aug 27 2018 firstname.lastname@example.com - Depend explicitly on zlib-devel, previously pulled in by openssl * Mon Jun 25 2018 firstname.lastname@example.com - BuildRequire pkgconfig(krb5) instead of krb5-mini-devel to ensure zypper si can pick a resolvable provider. Build cycle remains solved via project config pulling in -mini. (bsc#1099044) * Mon May 21 2018 firstname.lastname@example.com - Upgrade to 7.7p1 (bsc#1094068) Most important changes (more details below): * Drop compatibility support for pre-2001 SSH implementations * sshd(1) does not load DSA keys by default Distilled upstream log: - --- Potentially-incompatible changes * ssh(1)/sshd(8): Drop compatibility support for some very old SSH implementations, including ssh.com <=2.* and OpenSSH <= 3.*. These versions were all released in or before 2001 and predate the final SSH RFCs. The support in question isn't necessary for RFC-compliant SSH implementations. - --- New Features * experimental support for PQC XMSS keys (Extended Hash-Based Signatures), not compiled in by default. * sshd(8): Add a "rdomain" criteria for the sshd_config Match keyword to allow conditional configuration that depends on which routing domain a connection was received on (currently supported on OpenBSD and Linux). * sshd_config(5): Add an optional rdomain qualifier to the ListenAddress directive to allow listening on different routing domains. This is supported only on OpenBSD and Linux at present. * sshd_config(5): Add RDomain directive to allow the authenticated session to be placed in an explicit routing domain. This is only supported on OpenBSD at present. * sshd(8): Add "expiry-time" option for authorized_keys files to allow for expiring keys. * ssh(1): Add a BindInterface option to allow binding the outgoing connection to an interface's address (basically a more usable BindAddress) * ssh(1): Expose device allocated for tun/tap forwarding via a new %T expansion for LocalCommand. This allows LocalCommand to be %used to prepare the interface. * sshd(8): Expose the device allocated for tun/tap forwarding via a new SSH_TUNNEL environment variable. This allows automatic setup of the interface and surrounding network configuration automatically on the server. * ssh(1)/scp(1)/sftp(1): Add URI support to ssh, sftp and scp, e.g. ssh://user@host or sftp://user@host/path. Additional connection parameters that use deporecated MD5 are not implemented. * ssh-keygen(1): Allow certificate validity intervals that specify only a start or stop time (instead of both or neither). * sftp(1): Allow "cd" and "lcd" commands with no explicit path argument. lcd will change to the local user's home directory as usual. cd will change to the starting directory for session (because the protocol offers no way to obtain the remote user's home directory). bz#2760 * sshd(8): When doing a config test with sshd -T, only require the attributes that are actually used in Match criteria rather than (an incomplete list of) all criteria. - --- Bugfixes * ssh(1)/sshd(8): More strictly check signature types during key exchange against what was negotiated. Prevents downgrade of RSA signatures made with SHA-256/512 to SHA-1. * sshd(8): Fix support for client that advertise a protocol version of "1.99" (indicating that they are prepared to accept both SSHv1 and SSHv2). This was broken in OpenSSH 7.6 during the removal of SSHv1 support. bz#2810 * ssh(1): Warn when the agent returns a ssh-rsa (SHA1) signature when a rsa-sha2-256/512 signature was requested. This condition is possible when an old or non-OpenSSH agent is in use. bz#2799 * ssh-agent(1): Fix regression introduced in 7.6 that caused ssh-agent to fatally exit if presented an invalid signature request message. * sshd_config(5): Accept yes/no flag options case-insensitively, as has been the case in ssh_config(5) for a long time. bz#2664 * ssh(1): Improve error reporting for failures during connection. Under some circumstances misleading errors were being shown. bz#2814 * ssh-keyscan(1): Add -D option to allow printing of results directly in SSHFP format. bz#2821 * regress tests: fix PuTTY interop test broken in last release's SSHv1 removal. bz#2823 * ssh(1): Compatibility fix for some servers that erroneously drop the connection when the IUTF8 (RFC8160) option is sent. * scp(1): Disable RemoteCommand and RequestTTY in the ssh session started by scp (sftp was already doing this.) * ssh-keygen(1): Refuse to create a certificate with an unusable number of principals. * ssh-keygen(1): Fatally exit if ssh-keygen is unable to write all the public key during key generation. Previously it would silently ignore errors writing the comment and terminating newline. * ssh(1): Do not modify hostname arguments that are addresses by automatically forcing them to lower-case. Instead canonicalise them to resolve ambiguities (e.g. ::0001 => ::1) before they are matched against known_hosts. bz#2763 * ssh(1): Don't accept junk after "yes" or "no" responses to hostkey prompts. bz#2803 * sftp(1): Have sftp print a warning about shell cleanliness when decoding the first packet fails, which is usually caused by shells polluting stdout of non-interactive startups. bz#2800 * ssh(1)/sshd(8): Switch timers in packet code from using wall-clock time to monotonic time, allowing the packet layer to better function over a clock step and avoiding possible integer overflows during steps. * Numerous manual page fixes and improvements. * Wed May 02 2018 firstname.lastname@example.com - Use TIRPC on suse_version >= 1500: sunrpc is deprecated and should be replaced by TIRPC. * Mon Apr 30 2018 email@example.com - additional rebased patches (bsc#1080779) * auditing support * LDAP integration * various distribution tweaks from SLE12 (X forwarding over IPv6, sftp forced permissions and verbose batch mode) * Wed Apr 04 2018 email@example.com - Use %license instead of %doc [bsc#1082318] * Mon Feb 12 2018 firstname.lastname@example.com - add OpenSSL 1.0 to 1.1 shim to remove dependency on old OpenSSL (update tracker: bsc#1080779) * Wed Jan 31 2018 firstname.lastname@example.com - Add missing crypto hardware enablement patches for IBM mainframes (FATE#323902) * Wed Jan 24 2018 email@example.com - add missing part of systemd integration (unit type) * Tue Jan 16 2018 firstname.lastname@example.com - BuildRequire pkgconfig(libsystemd) instead of systemd-devel: allow the scheduler to pick systemd-mini flavors to get build going. * Fri Jan 12 2018 email@example.com - Replace forgotten references to /var/adm/fillup-templates with new %_fillupdir macro (boo#1069468) - tighten configuration access rights * Thu Jan 11 2018 firstname.lastname@example.com - Update to vanilla 7.6p1 Most important changes (more details below): * complete removal of the ancient SSHv1 protocol * sshd(8) cannot run without privilege separation * removal of suport for arcfourm blowfish and CAST ciphers and RIPE-MD160 HMAC * refuse RSA keys shorter than 1024 bits Distilled upstream log: - OpenSSH 7.3 - --- Security * sshd(8): Mitigate a potential denial-of-service attack against the system's crypt(3) function via sshd(8). An attacker could send very long passwords that would cause excessive CPU use in crypt(3). sshd(8) now refuses to accept password authentication requests of length greater than 1024 characters. Independently reported by Tomas Kuthan (Oracle), Andres Rojas and Javier Nieto. * sshd(8): Mitigate timing differences in password authentication that could be used to discern valid from invalid account names when long passwords were sent and particular password hashing algorithms are in use on the server. CVE-2016-6210, reported by EddieEzra.Harari at verint.com * ssh(1), sshd(8): Fix observable timing weakness in the CBC padding oracle countermeasures. Reported by Jean Paul Degabriele, Kenny Paterson, Torben Hansen and Martin Albrecht. Note that CBC ciphers are disabled by default and only included for legacy compatibility. * ssh(1), sshd(8): Improve operation ordering of MAC verification for Encrypt-then-MAC (EtM) mode transport MAC algorithms to verify the MAC before decrypting any ciphertext. This removes the possibility of timing differences leaking facts about the plaintext, though no such leakage has been observed. Reported by Jean Paul Degabriele, Kenny Paterson, Torben Hansen and Martin Albrecht. * sshd(8): (portable only) Ignore PAM environment vars when UseLogin=yes. If PAM is configured to read user-specified environment variables and UseLogin=yes in sshd_config, then a hostile local user may attack /bin/login via LD_PRELOAD or similar environment variables set via PAM. CVE-2015-8325, found by Shayan Sadigh. - --- New Features * ssh(1): Add a ProxyJump option and corresponding -J command-line flag to allow simplified indirection through a one or more SSH bastions or "jump hosts". * ssh(1): Add an IdentityAgent option to allow specifying specific agent sockets instead of accepting one from the environment. * ssh(1): Allow ExitOnForwardFailure and ClearAllForwardings to be optionally overridden when using ssh -W. bz#2577 * ssh(1), sshd(8): Implement support for the IUTF8 terminal mode as per draft-sgtatham-secsh-iutf8-00. * ssh(1), sshd(8): Add support for additional fixed Diffie-Hellman 2K, 4K and 8K groups from draft-ietf-curdle-ssh-kex-sha2-03. * ssh-keygen(1), ssh(1), sshd(8): support SHA256 and SHA512 RSA signatures in certificates; * ssh(1): Add an Include directive for ssh_config(5) files. * ssh(1): Permit UTF-8 characters in pre-authentication banners sent from the server. bz#2058 - --- Bugfixes * ssh(1), sshd(8): Reduce the syslog level of some relatively common protocol events from LOG_CRIT. bz#2585 * sshd(8): Refuse AuthenticationMethods="" in configurations and accept AuthenticationMethods=any for the default behaviour of not requiring multiple authentication. bz#2398 * sshd(8): Remove obsolete and misleading "POSSIBLE BREAK-IN ATTEMPT!" message when forward and reverse DNS don't match. bz#2585 * ssh(1): Close ControlPersist background process stderr except in debug mode or when logging to syslog. bz#1988 * misc: Make PROTOCOL description for firstname.lastname@example.com channel open messages match deployed code. bz#2529 * ssh(1): Deduplicate LocalForward and RemoteForward entries to fix failures when both ExitOnForwardFailure and hostname canonicalisation are enabled. bz#2562 * sshd(8): Remove fallback from moduli to obsolete "primes" file that was deprecated in 2001. bz#2559. * sshd_config(5): Correct description of UseDNS: it affects ssh hostname processing for authorized_keys, not known_hosts; bz#2554 * ssh(1): Fix authentication using lone certificate keys in an agent without corresponding private keys on the filesystem. bz#2550 * sshd(8): Send ClientAliveInterval pings when a time-based RekeyLimit is set; previously keepalive packets were not being sent. bz#2252 - --- Portability * ssh(1), sshd(8): Fix compilation by automatically disabling ciphers not supported by OpenSSL. bz#2466 * misc: Fix compilation failures on some versions of AIX's compiler related to the definition of the VA_COPY macro. bz#2589 * sshd(8): Whitelist more architectures to enable the seccomp-bpf sandbox. bz#2590 * ssh-agent(1), sftp-server(8): Disable process tracing on Solaris using setpflags(__PROC_PROTECT, ...). bz#2584 * sshd(8): On Solaris, don't call Solaris setproject() with UsePAM=yes it's PAM's responsibility. bz#2425 - OpenSSH 7.4 - --- Potentially-incompatible changes * ssh(1): Remove 3des-cbc from the client's default proposal. 64-bit block ciphers are not safe in 2016 and we don't want to wait until attacks like SWEET32 are extended to SSH. As 3des-cbc was the only mandatory cipher in the SSH RFCs, this may cause problems connecting to older devices using the default configuration, but it's highly likely that such devices already need explicit configuration for key exchange and hostkey algorithms already anyway. * sshd(8): Remove support for pre-authentication compression. Doing compression early in the protocol probably seemed reasonable in the 1990s, but today it's clearly a bad idea in terms of both cryptography (cf. multiple compression oracle attacks in TLS) and attack surface. Pre-auth compression support has been disabled by default for >10 years. Support remains in the client. * ssh-agent will refuse to load PKCS#11 modules outside a whitelist of trusted paths by default. The path whitelist may be specified at run-time. * sshd(8): When a forced-command appears in both a certificate and an authorized keys/principals command= restriction, sshd will now refuse to accept the certificate unless they are identical. The previous (documented) behaviour of having the certificate forced-command override the other could be a bit confusing and error-prone. * sshd(8): Remove the UseLogin configuration directive and support for having /bin/login manage login sessions. - --- Security * ssh-agent(1): Will now refuse to load PKCS#11 modules from paths outside a trusted whitelist (run-time configurable). Requests to load modules could be passed via agent forwarding and an attacker could attempt to load a hostile PKCS#11 module across the forwarded agent channel: PKCS#11 modules are shared libraries, so this would result in code execution on the system running the ssh-agent if the attacker has control of the forwarded agent-socket (on the host running the sshd server) and the ability to write to the filesystem of the host running ssh-agent (usually the host running the ssh client). Reported by Jann Horn of Project Zero. * sshd(8): When privilege separation is disabled, forwarded Unix- domain sockets would be created by sshd(8) with the privileges of 'root' instead of the authenticated user. This release refuses Unix-domain socket forwarding when privilege separation is disabled (Privilege separation has been enabled by default for 14 years). Reported by Jann Horn of Project Zero. * sshd(8): Avoid theoretical leak of host private key material to privilege-separated child processes via realloc() when reading keys. No such leak was observed in practice for normal-sized keys, nor does a leak to the child processes directly expose key material to unprivileged users. Reported by Jann Horn of Project Zero. * sshd(8): The shared memory manager used by pre-authentication compression support had a bounds checks that could be elided by some optimising compilers. Additionally, this memory manager was incorrectly accessible when pre-authentication compression was disabled. This could potentially allow attacks against the privileged monitor process from the sandboxed privilege-separation process (a compromise of the latter would be required first). This release removes support for pre-authentication compression from sshd(8). Reported by Guido Vranken using the Stack unstable optimisation identification tool (http://css.csail.mit.edu/stack/) * sshd(8): Fix denial-of-service condition where an attacker who sends multiple KEXINIT messages may consume up to 128MB per connection. Reported by Shi Lei of Gear Team, Qihoo 360. * sshd(8): Validate address ranges for AllowUser and DenyUsers directives at configuration load time and refuse to accept invalid ones. It was previously possible to specify invalid CIDR address ranges (e.g. email@example.com/55) and these would always match, possibly resulting in granting access where it was not intended. Reported by Laurence Parry. - --- New Features * ssh(1): Add a proxy multiplexing mode to ssh(1) inspired by the version in PuTTY by Simon Tatham. This allows a multiplexing client to communicate with the master process using a subset of the SSH packet and channels protocol over a Unix-domain socket, with the main process acting as a proxy that translates channel IDs, etc. This allows multiplexing mode to run on systems that lack file- descriptor passing (used by current multiplexing code) and potentially, in conjunction with Unix-domain socket forwarding, with the client and multiplexing master process on different machines. Multiplexing proxy mode may be invoked using "ssh -O proxy ..." * sshd(8): Add a sshd_config DisableForwarding option that disables X11, agent, TCP, tunnel and Unix domain socket forwarding, as well as anything else we might implement in the future. Like the 'restrict' authorized_keys flag, this is intended to be a simple and future-proof way of restricting an account. * sshd(8), ssh(1): Support the "curve25519-sha256" key exchange method. This is identical to the currently-supported method named "firstname.lastname@example.com". * sshd(8): Improve handling of SIGHUP by checking to see if sshd is already daemonised at startup and skipping the call to daemon(3) if it is. This ensures that a SIGHUP restart of sshd(8) will retain the same process-ID as the initial execution. sshd(8) will also now unlink the PidFile prior to SIGHUP restart and re-create it after a successful restart, rather than leaving a stale file in the case of a configuration error. bz#2641 * sshd(8): Allow ClientAliveInterval and ClientAliveCountMax directives to appear in sshd_config Match blocks. * sshd(8): Add %-escapes to AuthorizedPrincipalsCommand to match those supported by AuthorizedKeysCommand (key, key type, fingerprint, etc.) and a few more to provide access to the contents of the certificate being offered. * Added regression tests for string matching, address matching and string sanitisation functions. * Improved the key exchange fuzzer harness. - --- Bugfixes * ssh(1): Allow IdentityFile to successfully load and use certificates that have no corresponding bare public key. bz#2617 certificate id_rsa-cert.pub (and no id_rsa.pub). * ssh(1): Fix public key authentication when multiple authentication is in use and publickey is not just the first method attempted. bz#2642 * regress: Allow the PuTTY interop tests to run unattended. bz#2639 * ssh-agent(1), ssh(1): improve reporting when attempting to load keys from PKCS#11 tokens with fewer useless log messages and more detail in debug messages. bz#2610 * ssh(1): When tearing down ControlMaster connections, don't pollute stderr when LogLevel=quiet. * sftp(1): On ^Z wait for underlying ssh(1) to suspend before suspending sftp(1) to ensure that ssh(1) restores the terminal mode correctly if suspended during a password prompt. * ssh(1): Avoid busy-wait when ssh(1) is suspended during a password prompt. * ssh(1), sshd(8): Correctly report errors during sending of ext- info messages. * sshd(8): fix NULL-deref crash if sshd(8) received an out-of- sequence NEWKEYS message. * sshd(8): Correct list of supported signature algorithms sent in the server-sig-algs extension. bz#2547 * sshd(8): Fix sending ext_info message if privsep is disabled. * sshd(8): more strictly enforce the expected ordering of privilege separation monitor calls used for authentication and allow them only when their respective authentication methods are enabled in the configuration * sshd(8): Fix uninitialised optlen in getsockopt() call; harmless on Unix/BSD but potentially crashy on Cygwin. * Fix false positive reports caused by explicit_bzero(3) not being recognised as a memory initialiser when compiled with - fsanitize-memory. * sshd_config(5): Use 2001:db8::/32, the official IPv6 subnet for configuration examples. - --- Portability * On environments configured with Turkish locales, fall back to the C/POSIX locale to avoid errors in configuration parsing caused by that locale's unique handling of the letters 'i' and 'I'. bz#2643 * sftp-server(8), ssh-agent(1): Deny ptrace on OS X using ptrace(PT_DENY_ATTACH, ..) * ssh(1), sshd(8): Unbreak AES-CTR ciphers on old (~0.9.8) OpenSSL. * Fix compilation for libcrypto compiled without RIPEMD160 support. * contrib: Add a gnome-ssh-askpass3 with GTK+3 support. bz#2640 * sshd(8): Improve PRNG reseeding across privilege separation and force libcrypto to obtain a high-quality seed before chroot or sandboxing. * All: Explicitly test for broken strnvis. NetBSD added an strnvis and unfortunately made it incompatible with the existing one in OpenBSD and Linux's libbsd (the former having existed for over ten years). Try to detect this mess, and assume the only safe option if we're cross compiling. - OpenSSH 7.5 - --- Potentially-incompatible changes * This release deprecates the sshd_config UsePrivilegeSeparation option, thereby making privilege separation mandatory. Privilege separation has been on by default for almost 15 years and sandboxing has been on by default for almost the last five. * The format of several log messages emitted by the packet code has changed to include additional information about the user and their authentication state. Software that monitors ssh/sshd logs may need to account for these changes. For example: Connection closed by user x 18.104.22.168 port 1234 [preauth] Connection closed by authenticating user x 10.1.1.1 port 1234 [preauth] Connection closed by invalid user x 184.108.40.206 port 1234 [preauth] Affected messages include connection closure, timeout, remote disconnection, negotiation failure and some other fatal messages generated by the packet code. * [Portable OpenSSH only] This version removes support for building against OpenSSL versions prior to 1.0.1. OpenSSL stopped supporting versions prior to 1.0.1 over 12 months ago (i.e. they no longer receive fixes for security bugs). - --- Security * ssh(1), sshd(8): Fix weakness in CBC padding oracle countermeasures that allowed a variant of the attack fixed in OpenSSH 7.3 to proceed. Note that the OpenSSH client disables CBC ciphers by default, sshd offers them as lowest-preference options and will remove them by default entriely in the next release. Reported by Jean Paul Degabriele, Kenny Paterson, Martin Albrecht and Torben Hansen of Royal Holloway, University of London. * sftp-client(1): [portable OpenSSH only] On Cygwin, a client making a recursive file transfer could be maniuplated by a hostile server to perform a path-traversal attack. creating or modifying files outside of the intended target directory. Reported by Jann Horn of Google Project Zero. - --- New Features * ssh(1), sshd(8): Support "=-" syntax to easily remove methods from algorithm lists, e.g. Ciphers=-*cbc. bz#2671 - --- Bugfixes * sshd(1): Fix NULL dereference crash when key exchange start messages are sent out of sequence. * ssh(1), sshd(8): Allow form-feed characters to appear in configuration files. * sshd(8): Fix regression in OpenSSH 7.4 support for the server-sig-algs extension, where SHA2 RSA signature methods were not being correctly advertised. bz#2680 * ssh(1), ssh-keygen(1): Fix a number of case-sensitivity bugs in known_hosts processing. bz#2591 bz#2685 * ssh(1): Allow ssh to use certificates accompanied by a private key file but no corresponding plain *.pub public key. bz#2617 * ssh(1): When updating hostkeys using the UpdateHostKeys option, accept RSA keys if HostkeyAlgorithms contains any RSA keytype. Previously, ssh could ignore RSA keys when only the ssh-rsa-sha2-* methods were enabled in HostkeyAlgorithms and not the old ssh-rsa method. bz#2650 * ssh(1): Detect and report excessively long configuration file lines. bz#2651 * Merge a number of fixes found by Coverity and reported via Redhat and FreeBSD. Includes fixes for some memory and file descriptor leaks in error paths. bz#2687 * ssh-keyscan(1): Correctly hash hosts with a port number. bz#2692 * ssh(1), sshd(8): When logging long messages to stderr, don't truncate "\r\n" if the length of the message exceeds the buffer. bz#2688 * ssh(1): Fully quote [host]:port in generated ProxyJump/-J command- line; avoid confusion over IPv6 addresses and shells that treat square bracket characters specially. * ssh-keygen(1): Fix corruption of known_hosts when running "ssh-keygen -H" on a known_hosts containing already-hashed entries. * Fix various fallout and sharp edges caused by removing SSH protocol 1 support from the server, including the server banner string being incorrectly terminated with only \n (instead of \r\n), confusing error messages from ssh-keyscan bz#2583 and a segfault in sshd if protocol v.1 was enabled for the client and sshd_config contained references to legacy keys bz#2686. * ssh(1), sshd(8): Free fd_set on connection timeout. bz#2683 * sshd(8): Fix Unix domain socket forwarding for root (regression in OpenSSH 7.4). * sftp(1): Fix division by zero crash in "df" output when server returns zero total filesystem blocks/inodes. * ssh(1), ssh-add(1), ssh-keygen(1), sshd(8): Translate OpenSSL errors encountered during key loading to more meaningful error codes. bz#2522 bz#2523 * ssh-keygen(1): Sanitise escape sequences in key comments sent to printf but preserve valid UTF-8 when the locale supports it; bz#2520 * ssh(1), sshd(8): Return reason for port forwarding failures where feasible rather than always "administratively prohibited". bz#2674 * sshd(8): Fix deadlock when AuthorizedKeysCommand or AuthorizedPrincipalsCommand produces a lot of output and a key is matched early. bz#2655 * Regression tests: several reliability fixes. bz#2654 bz#2658 bz#2659 * ssh(1): Fix typo in ~C error message for bad port forward cancellation. bz#2672 * ssh(1): Show a useful error message when included config files can't be opened; bz#2653 * sshd(8): Make sshd set GSSAPIStrictAcceptorCheck=yes as the manual page (previously incorrectly) advertised. bz#2637 * sshd_config(5): Repair accidentally-deleted mention of %k token in AuthorizedKeysCommand; bz#2656 * sshd(8): Remove vestiges of previously removed LOGIN_PROGRAM; bz#2665 * ssh-agent(1): Relax PKCS#11 whitelist to include libexec and common 32-bit compatibility library directories. * sftp-client(1): Fix non-exploitable integer overflow in SSH2_FXP_NAME response handling. * ssh-agent(1): Fix regression in 7.4 of deleting PKCS#11-hosted keys. It was not possible to delete them except by specifying their full physical path. bz#2682 - --- Portability * sshd(8): Avoid sandbox errors for Linux S390 systems using an ICA crypto coprocessor. * sshd(8): Fix non-exploitable weakness in seccomp-bpf sandbox arg inspection. * ssh(1): Fix X11 forwarding on OSX where X11 was being started by launchd. bz#2341 * ssh-keygen(1), ssh(1), sftp(1): Fix output truncation for various that contain non-printable characters where the codeset in use is ASCII. * build: Fix builds that attempt to link a kerberised libldns. bz#2603 * build: Fix compilation problems caused by unconditionally defining _XOPEN_SOURCE in wide character detection. * sshd(8): Fix sandbox violations for clock_gettime VSDO syscall fallback on some Linux/X32 kernels. bz#2142 - OpenSSH 7.6 - --- Potentially-incompatible changes This release includes a number of changes that may affect existing configurations: * ssh(1): delete SSH protocol version 1 support, associated configuration options and documentation. * ssh(1)/sshd(8): remove support for the hmac-ripemd160 MAC. * ssh(1)/sshd(8): remove support for the arcfour, blowfish and CAST ciphers. * Refuse RSA keys <1024 bits in length and improve reporting for keys that do not meet this requirement. * ssh(1): do not offer CBC ciphers by default. - --- Security * sftp-server(8): in read-only mode, sftp-server was incorrectly permitting creation of zero-length files. Reported by Michal Zalewski. - --- New Features * ssh(1): add RemoteCommand option to specify a command in the ssh config file instead of giving it on the client's command line. This allows the configuration file to specify the command that will be executed on the remote host. * sshd(8): add ExposeAuthInfo option that enables writing details of the authentication methods used (including public keys where applicable) to a file that is exposed via a $SSH_USER_AUTH environment variable in the subsequent session. * ssh(1): add support for reverse dynamic forwarding. In this mode, ssh will act as a SOCKS4/5 proxy and forward connections to destinations requested by the remote SOCKS client. This mode is requested using extended syntax for the - R and RemoteForward options and, because it is implemented solely at the client, does not require the server be updated to be supported. * sshd(8): allow LogLevel directive in sshd_config Match blocks; bz#2717 * ssh-keygen(1): allow inclusion of arbitrary string or flag certificate extensions and critical options. * ssh-keygen(1): allow ssh-keygen to use a key held in ssh-agent as a CA when signing certificates. bz#2377 * ssh(1)/sshd(8): allow IPQoS=none in ssh/sshd to not set an explicit ToS/DSCP value and just use the operating system default. * ssh-add(1): added -q option to make ssh-add quiet on success. * ssh(1): expand the StrictHostKeyChecking option with two new settings. The first "accept-new" will automatically accept hitherto-unseen keys but will refuse connections for changed or invalid hostkeys. This is a safer subset of the current behaviour of StrictHostKeyChecking=no. The second setting "off", is a synonym for the current behaviour of StrictHostKeyChecking=no: accept new host keys, and continue connection for hosts with incorrect hostkeys. A future release will change the meaning of StrictHostKeyChecking=no to the behaviour of "accept-new". bz#2400 * ssh(1): add SyslogFacility option to ssh(1) matching the equivalent option in sshd(8). bz#2705 - --- Bugfixes * ssh(1): use HostKeyAlias if specified instead of hostname for matching host certificate principal names; bz#2728 * sftp(1): implement sorting for globbed ls; bz#2649 * ssh(1): add a user@host prefix to client's "Permission denied" messages, useful in particular when using "stacked" connections (e.g. ssh -J) where it's not clear which host is denying. bz#2720 * ssh(1): accept unknown EXT_INFO extension values that contain \0 characters. These are legal, but would previously cause fatal connection errors if received. * ssh(1)/sshd(8): repair compression statistics printed at connection exit * sftp(1): print '?' instead of incorrect link count (that the protocol doesn't provide) for remote listings. bz#2710 * ssh(1): return failure rather than fatal() for more cases during session multiplexing negotiations. Causes the session to fall back to a non-mux connection if they occur. bz#2707 * ssh(1): mention that the server may send debug messages to explain public key authentication problems under some circumstances; bz#2709 * Translate OpenSSL error codes to better report incorrect passphrase errors when loading private keys; bz#2699 * sshd(8): adjust compatibility patterns for WinSCP to correctly identify versions that implement only the legacy DH group exchange scheme. bz#2748 * ssh(1): print the "Killed by signal 1" message only at LogLevel verbose so that it is not shown at the default level; prevents it from appearing during ssh -J and equivalent ProxyCommand configs. bz#1906, bz#2744 * ssh-keygen(1): when generating all hostkeys (ssh-keygen -A), clobber existing keys if they exist but are zero length. zero-length keys could previously be made if ssh-keygen failed or was interrupted part way through generating them. bz#2561 * ssh(1): fix pledge(2) violation in the escape sequence "~&" used to place the current session in the background. * ssh-keyscan(1): avoid double-close() on file descriptors; bz#2734 * sshd(8): avoid reliance on shared use of pointers shared between monitor and child sshd processes. bz#2704 * sshd_config(8): document available AuthenticationMethods; bz#2453 * ssh(1): avoid truncation in some login prompts; bz#2768 * sshd(8): Fix various compilations failures, inc bz#2767 * ssh(1): make "--" before the hostname terminate argument processing after the hostname too. * ssh-keygen(1): switch from aes256-cbc to aes256-ctr for encrypting new-style private keys. Fixes problems related to private key handling for no-OpenSSL builds. bz#2754 * ssh(1): warn and do not attempt to use keys when the public and private halves do not match. bz#2737 * sftp(1): don't print verbose error message when ssh disconnects from under sftp. bz#2750 * sshd(8): fix keepalive scheduling problem: activity on a forwarded port from preventing the keepalive from being sent; bz#2756 * sshd(8): when started without root privileges, don't require the privilege separation user or path to exist. Makes running the regression tests easier without touching the filesystem. * Make integrity.sh regression tests more robust against timeouts. bz#2658 * ssh(1)/sshd(8): correctness fix for channels implementation: accept channel IDs greater than 0x7FFFFFFF. - --- Portability * sshd(9): drop two more privileges in the Solaris sandbox: PRIV_DAX_ACCESS and PRIV_SYS_IB_INFO; bz#2723 * sshd(8): expose list of completed authentication methods to PAM via the SSH_AUTH_INFO_0 PAM environment variable. bz#2408 * ssh(1)/sshd(8): fix several problems in the tun/tap forwarding code, mostly to do with host/network byte order confusion. bz#2735 * Add --with-cflags-after and --with-ldflags-after configure flags to allow setting CFLAGS/LDFLAGS after configure has completed. These are useful for setting sanitiser/fuzzing options that may interfere with configure's operation. * sshd(8): avoid Linux seccomp violations on ppc64le over the socketcall syscall. * Fix use of ldns when using ldns-config; bz#2697 * configure: set cache variables when cross-compiling. The cross- compiling fallback message was saying it assumed the test passed, but it wasn't actually set the cache variables and this would cause later tests to fail. * Add clang libFuzzer harnesses for public key parsing and signature verification. - packaging: * moving patches into a separate archive * first round of rebased patches: [-X11_trusted_forwarding] [-allow_root_password_login] [-blocksigalrm] [-cavstest-ctr] [-cavstest-kdf] [-disable_short_DH_parameters] [-eal3] [-enable_PAM_by_default] [-fips] [-fips_checks] [-gssapi_key_exchange] [-hostname_changes_when_forwarding_X] [-lastlog] [-missing_headers] [-pam_check_locks] [-pts_names_formatting] [-remove_xauth_cookies_on_exit] [-seccomp_geteuid] [-seccomp_getuid] [-seccomp_stat] [-seed-prng] [-send_locale] [-systemd-notify] * not rebased (obsoleted) patches (so far): [-additional_seccomp_archs] [-allow_DSS_by_default] [-default_protocol] [-dont_use_pthreads_in_PAM] [-eal3_obsolete] [-gssapimitm] [-saveargv-fix] * obviously removing all standalone patch files: [openssh-7.2p2-allow_root_password_login.patch] [openssh-7.2p2-allow_DSS_by_default.patch] [openssh-7.2p2-X11_trusted_forwarding.patch] [openssh-7.2p2-lastlog.patch] [openssh-7.2p2-enable_PAM_by_default.patch] [openssh-7.2p2-dont_use_pthreads_in_PAM.patch] [openssh-7.2p2-eal3.patch] [openssh-7.2p2-blocksigalrm.patch] [openssh-7.2p2-send_locale.patch] [openssh-7.2p2-hostname_changes_when_forwarding_X.patch] [openssh-7.2p2-remove_xauth_cookies_on_exit.patch] [openssh-7.2p2-pts_names_formatting.patch] [openssh-7.2p2-pam_check_locks.patch] [openssh-7.2p2-disable_short_DH_parameters.patch] [openssh-7.2p2-seccomp_getuid.patch] [openssh-7.2p2-seccomp_geteuid.patch] [openssh-7.2p2-seccomp_stat.patch] [openssh-7.2p2-additional_seccomp_archs.patch] [openssh-7.2p2-fips.patch] [openssh-7.2p2-cavstest-ctr.patch] [openssh-7.2p2-cavstest-kdf.patch] [openssh-7.2p2-seed-prng.patch] [openssh-7.2p2-gssapi_key_exchange.patch] [openssh-7.2p2-audit.patch] [openssh-7.2p2-audit_fixes.patch] [openssh-7.2p2-audit_seed_prng.patch] [openssh-7.2p2-login_options.patch] [openssh-7.2p2-disable_openssl_abi_check.patch] [openssh-7.2p2-no_fork-no_pid_file.patch] [openssh-7.2p2-host_ident.patch] [openssh-7.2p2-sftp_homechroot.patch] [openssh-7.2p2-sftp_force_permissions.patch] [openssh-7.2p2-X_forward_with_disabled_ipv6.patch] [openssh-7.2p2-ldap.patch] [openssh-7.2p2-IPv6_X_forwarding.patch] [openssh-7.2p2-ignore_PAM_with_UseLogin.patch] [openssh-7.2p2-prevent_timing_user_enumeration.patch] [openssh-7.2p2-limit_password_length.patch] [openssh-7.2p2-keep_slogin.patch] [openssh-7.2p2-kex_resource_depletion.patch] [openssh-7.2p2-verify_CIDR_address_ranges.patch] [openssh-7.2p2-restrict_pkcs11-modules.patch] [openssh-7.2p2-prevent_private_key_leakage.patch] [openssh-7.2p2-secure_unix_sockets_forwarding.patch] [openssh-7.2p2-ssh_case_insensitive_host_matching.patch] [openssh-7.2p2-disable_preauth_compression.patch] [openssh-7.2p2-s390_hw_crypto_syscalls.patch] [openssh-7.2p2-s390_OpenSSL-ibmpkcs11_syscalls.patch] * Thu Nov 23 2017 firstname.lastname@example.com - Replace references to /var/adm/fillup-templates with new %_fillupdir macro (boo#1069468) * Wed Oct 25 2017 email@example.com - sshd_config is has now permissions 0600 in secure mode * Mon May 15 2017 firstname.lastname@example.com - Fix preauth seccomp separation on mainframes (bsc#1016709) [openssh-7.2p2-s390_hw_crypto_syscalls.patch] [openssh-7.2p2-s390_OpenSSL-ibmpkcs11_syscalls.patch] - enable case-insensitive hostname matching (bsc#1017099) [openssh-7.2p2-ssh_case_insensitive_host_matching.patch] - add CAVS tests [openssh-7.2p2-cavstest-ctr.patch] [openssh-7.2p2-cavstest-kdf.patch] - Adding missing pieces for user matching (bsc#1021626) - Properly verify CIDR masks in configuration (bsc#1005893) [openssh-7.2p2-verify_CIDR_address_ranges.patch] - Remove pre-auth compression support from the server to prevent possible cryptographic attacks.

In particular, CBC ciphers and arcfour* are disabled by default. The full set of algorithms remains available if configured explicitly via the Ciphers and MACs sshd_config options. * sshd(8): Support for tcpwrappers/libwrap has been removed. * OpenSSH 6.5 and 6.6 have a bug that causes ~0.2% of connections using the firstname.lastname@example.com KEX exchange method to fail when connecting with something that implements the specification correctly. OpenSSH 6.7 disables this KEX method when speaking to one of the affected versions. New Features: * ssh(1), sshd(8): Add support for Unix domain socket forwarding. A remote TCP port may be forwarded to a local Unix domain socket and vice versa or both ends may be a Unix domain socket. * ssh(1), ssh-keygen(1): Add support for SSHFP DNS records for ED25519 key types. * sftp(1): Allow resumption of interrupted uploads. * ssh(1): When rekeying, skip file/DNS lookups of the hostkey if it is the same as the one sent during initial key exchange * sshd(8): Allow explicit ::1 and 127.0.0.1 forwarding bind addresses when GatewayPorts=no; allows client to choose address family * sshd(8): Add a sshd_config PermitUserRC option to control whether ~/.ssh/rc is executed, mirroring the no-user-rc authorized_keys option * ssh(1): Add a %C escape sequence for LocalCommand and ControlPath that expands to a unique identifer based on a hash of the tuple of (local host, remote user, hostname, port). Helps avoid exceeding miserly pathname limits for Unix domain sockets in multiplexing control paths * sshd(8): Make the "Too many authentication failures" message include the user, source address, port and protocol in a format similar to the authentication success / failure messages Bugfixes: * sshd(8): Fix remote forwarding with the same listen port but different listen address. * ssh(1): Fix inverted test that caused PKCS#11 keys that were explicitly listed in ssh_config or on the commandline not to be preferred. * ssh-keygen(1): Fix bug in KRL generation: multiple consecutive revoked certificate serial number ranges could be serialised to an invalid format. Readers of a broken KRL caused by this bug will fail closed, so no should-have-been-revoked key will be accepted. * ssh(1): Reflect stdio-forward ("ssh -W host:port ...") failures in exit status. Previously we were always returning 0 * ssh(1), ssh-keygen(1): Make Ed25519 keys' title fit properly in the randomart border * ssh-agent(1): Only cleanup agent socket in the main agent process and not in any subprocesses it may have started (e.g. forked askpass). Fixes agent sockets being zapped when askpass processes fatal() * ssh-add(1): Make stdout line-buffered; saves partial output getting lost when ssh-add fatal()s part-way through (e.g. when listing keys from an agent that supports key types that ssh-add doesn't) * ssh-keygen(1): When hashing or removing hosts, don't choke on @revoked markers and don't remove @cert-authority markers * ssh(1): Don't fatal when hostname canonicalisation fails and a ProxyCommand is in use; continue and allow the ProxyCommand to connect anyway (e.g. to a host with a name outside the DNS behind a bastion) * scp(1): When copying local->remote fails during read, don't send uninitialised heap to the remote end. * sftp(1): Fix fatal "el_insertstr failed" errors when tab-completing filenames with a single quote char somewhere in the string * ssh-keyscan(1): Scan for Ed25519 keys by default. * ssh(1): When using VerifyHostKeyDNS with a DNSSEC resolver, down-convert any certificate keys to plain keys and attempt SSHFP resolution. Prevents a server from skipping SSHFP lookup and forcing a new-hostkey dialog by offering only certificate keys. - OpenSSH 6.8 Potentially-incompatible changes: * sshd(8): UseDNS now defaults to 'no'. Configurations that match against the client host name (via sshd_config or authorized_keys) may need to re-enable it or convert to matching against addresses. New Features: * Add FingerprintHash option to ssh(1) and sshd(8), and equivalent command-line flags to the other tools to control algorithm used for key fingerprints. The default changes from MD5 to SHA256 and format from hex to base64. Fingerprints now have the hash algorithm prepended. An example of the new format: SHA256:mVPwvezndPv/ARoIadVY98vAC0g+P/5633yTC4d/wXE Please note that visual host keys will also be different. * ssh(1), sshd(8): Experimental host key rotation support. Add a protocol extension for a server to inform a client of all its available host keys after authentication has completed. The client may record the keys in known_hosts, allowing it to upgrade to better host key algorithms and a server to gracefully rotate its keys. The client side of this is controlled by a UpdateHostkeys config option (default off). * ssh(1): Add a ssh_config HostbasedKeyType option to control which host public key types are tried during host-based authentication. * ssh(1), sshd(8): fix connection-killing host key mismatch errors when sshd offers multiple ECDSA keys of different lengths. * ssh(1): when host name canonicalisation is enabled, try to parse host names as addresses before looking them up for canonicalisation. fixes bz#2074 and avoiding needless DNS lookups in some cases. * ssh-keygen(1), sshd(8): Key Revocation Lists (KRLs) no longer require OpenSSH to be compiled with OpenSSL support. * ssh(1), ssh-keysign(8): Make ed25519 keys work for host based authentication. * sshd(8): SSH protocol v.1 workaround for the Meyer, et al, Bleichenbacher Side Channel Attack. Fake up a bignum key before RSA decryption. * sshd(8): Remember which public keys have been used for authentication and refuse to accept previously-used keys. This allows AuthenticationMethods=publickey,publickey to require that users authenticate using two _different_ public keys. * sshd(8): add sshd_config HostbasedAcceptedKeyTypes and PubkeyAcceptedKeyTypes options to allow sshd to control what public key types will be accepted. Currently defaults to all. * sshd(8): Don't count partial authentication success as a failure against MaxAuthTries. * ssh(1): Add RevokedHostKeys option for the client to allow text-file or KRL-based revocation of host keys. * ssh-keygen(1), sshd(8): Permit KRLs that revoke certificates by serial number or key ID without scoping to a particular CA. * ssh(1): Add a "Match canonical" criteria that allows ssh_config Match blocks to trigger only in the second config pass. * ssh(1): Add a -G option to ssh that causes it to parse its configuration and dump the result to stdout, similar to "sshd -T". * ssh(1): Allow Match criteria to be negated. E.g. "Match !host". * The regression test suite has been extended to cover more OpenSSH features. The unit tests have been expanded and now cover key exchange. Bugfixes: * ssh-keyscan(1): ssh-keyscan has been made much more robust again servers that hang or violate the SSH protocol. * ssh(1), ssh-keygen(1): Fix regression: Key path names were being lost as comment fields. * ssh(1): Allow ssh_config Port options set in the second config parse phase to be applied (they were being ignored). * ssh(1): Tweak config re-parsing with host canonicalisation - make the second pass through the config files always run when host name canonicalisation is enabled (and not whenever the host name changes) * ssh(1): Fix passing of wildcard forward bind addresses when connection multiplexing is in use * ssh-keygen(1): Fix broken private key conversion from non-OpenSSH formats. * ssh-keygen(1): Fix KRL generation bug when multiple CAs are in use. * Various fixes to manual pages - OpenSSH 6.9 Security: * ssh(1): when forwarding X11 connections with ForwardX11Trusted=no, connections made after ForwardX11Timeout expired could be permitted and no longer subject to XSECURITY restrictions because of an ineffective timeout check in ssh(1) coupled with "fail open" behaviour in the X11 server when clients attempted connections with expired credentials. This problem was reported by Jann Horn. * ssh-agent(1): fix weakness of agent locking (ssh-add -x) to password guessing by implementing an increasing failure delay, storing a salted hash of the password rather than the password itself and using a timing-safe comparison function for verifying unlock attempts. This problem was reported by Ryan Castellucci. New Features: * ssh(1), sshd(8): promote email@example.com to be the default cipher * sshd(8): support admin-specified arguments to AuthorizedKeysCommand * sshd(8): add AuthorizedPrincipalsCommand that allows retrieving authorized principals information from a subprocess rather than a file. * ssh(1), ssh-add(1): support PKCS#11 devices with external PIN entry devices * sshd(8): allow GSSAPI host credential check to be relaxed for multihomed hosts via GSSAPIStrictAcceptorCheck option * ssh-keygen(1): support "ssh-keygen -lF hostname" to search known_hosts and print key hashes rather than full keys. * ssh-agent(1): add -D flag to leave ssh-agent in foreground without enabling debug mode Bugfixes: * ssh(1), sshd(8): deprecate legacy SSH2_MSG_KEX_DH_GEX_REQUEST_OLD message and do not try to use it against some 3rd-party SSH implementations that use it (older PuTTY, WinSCP). * Many fixes for problems caused by compile-time deactivation of SSH1 support (including bz#2369) * ssh(1), sshd(8): cap DH-GEX group size at 4Kbits for Cisco implementations as some would fail when attempting to use group sizes >4K * ssh(1): fix out-of-bound read in EscapeChar configuration option parsing * sshd(8): fix application of PermitTunnel, LoginGraceTime, AuthenticationMethods and StreamLocalBindMask options in Match blocks * ssh(1), sshd(8): improve disconnection message on TCP reset; bz#2257 * ssh(1): remove failed remote forwards established by muliplexing from the list of active forwards * sshd(8): make parsing of authorized_keys "environment=" options independent of PermitUserEnv being enabled * sshd(8): fix post-auth crash with permitopen=none * ssh(1), ssh-add(1), ssh-keygen(1): allow new-format private keys to be encrypted with AEAD ciphers * ssh(1): allow ListenAddress, Port and AddressFamily configuration options to appear in any order * sshd(8): check for and reject missing arguments for VersionAddendum and ForceCommand * ssh(1), sshd(8): don't treat unknown certificate extensions as fatal * ssh-keygen(1): make stdout and stderr output consistent * ssh(1): mention missing DISPLAY environment in debug log when X11 forwarding requested * sshd(8): correctly record login when UseLogin is set * sshd(8): Add some missing options to sshd -T output and fix output of VersionAddendum and HostCertificate. bz#2346 * Document and improve consistency of options that accept a "none" argument" TrustedUserCAKeys, RevokedKeys (bz#2382), AuthorizedPrincipalsFile (bz#2288) * ssh(1): include remote username in debug output * sshd(8): avoid compatibility problem with some versions of Tera Term, which would crash when they received the hostkeys notification message (email@example.com) * sshd(8): mention ssh-keygen -E as useful when comparing legacy MD5 host key fingerprints * ssh(1): clarify pseudo-terminal request behaviour and use make manual language consistent * ssh(1): document that the TERM environment variable is not subject to SendEnv and AcceptEnv - OpenSSH 7.0: This focuses primarily on deprecating weak, legacy and/or unsafe cryptography. Security: * sshd(8): OpenSSH 6.8 and 6.9 incorrectly set TTYs to be world- writable. Local attackers may be able to write arbitrary messages to logged-in users, including terminal escape sequences. Reported by Nikolay Edigaryev. * sshd(8): Portable OpenSSH only: Fixed a privilege separation weakness related to PAM support. Attackers who could successfully compromise the pre-authentication process for remote code execution and who had valid credentials on the host could impersonate other users. Reported by Moritz Jodeit. * sshd(8): Portable OpenSSH only: Fixed a use-after-free bug related to PAM support that was reachable by attackers who could compromise the pre-authentication process for remote code execution. Also reported by Moritz Jodeit. * sshd(8): fix circumvention of MaxAuthTries using keyboard- interactive authentication. By specifying a long, repeating keyboard-interactive "devices" string, an attacker could request the same authentication method be tried thousands of times in a single pass. The LoginGraceTime timeout in sshd(8) and any authentication failure delays implemented by the authentication mechanism itself were still applied. Found by Kingcope. Potentially-incompatible Changes: * Support for the legacy SSH version 1 protocol is disabled by default at compile time. * Support for the 1024-bit diffie-hellman-group1-sha1 key exchange is disabled by default at run-time. It may be re-enabled using the instructions in README.legacy or http://www.openssh.com/legacy.html * Support for ssh-dss, ssh-dss-cert-* host and user keys is disabled by default at run-time. These may be re-enabled using the instructions at http://www.openssh.com/legacy.html * Support for the legacy v00 cert format has been removed. * The default for the sshd_config(5) PermitRootLogin option has changed from "yes" to "prohibit-password". * PermitRootLogin=without-password/prohibit-password now bans all interactive authentication methods, allowing only public-key, hostbased and GSSAPI authentication (previously it permitted keyboard-interactive and password-less authentication if those were enabled). New Features: * ssh_config(5): add PubkeyAcceptedKeyTypes option to control which public key types are available for user authentication. * sshd_config(5): add HostKeyAlgorithms option to control which public key types are offered for host authentications. * ssh(1), sshd(8): extend Ciphers, MACs, KexAlgorithms, HostKeyAlgorithms, PubkeyAcceptedKeyTypes and HostbasedKeyTypes options to allow appending to the default set of algorithms instead of replacing it. Options may now be prefixed with a '+' to append to the default, e.g. "HostKeyAlgorithms=+ssh-dss". * sshd_config(5): PermitRootLogin now accepts an argument of 'prohibit-password' as a less-ambiguous synonym of 'without- password'. Bugfixes: * ssh(1), sshd(8): add compatability workarounds for Cisco and more PuTTY versions. * Fix some omissions and errors in the PROTOCOL and PROTOCOL.mux documentation relating to Unix domain socket forwarding * ssh(1): Improve the ssh(1) manual page to include a better description of Unix domain socket forwarding * ssh(1), ssh-agent(1): skip uninitialised PKCS#11 slots, fixing failures to load keys when they are present. * ssh(1), ssh-agent(1): do not ignore PKCS#11 hosted keys that wth empty CKA_ID * sshd(8): clarify documentation for UseDNS option - OpenSSH 7.1: Security: * sshd(8): OpenSSH 7.0 contained a logic error in PermitRootLogin= prohibit-password/without-password that could, depending on compile-time configuration, permit password authentication to root while preventing other forms of authentication. This problem was reported by Mantas Mikulenas. Bugfixes: * ssh(1), sshd(8): add compatability workarounds for FuTTY * ssh(1), sshd(8): refine compatability workarounds for WinSCP * Fix a number of memory faults (double-free, free of uninitialised memory, etc) in ssh(1) and ssh-keygen(1). Reported by Mateusz Kocielski. - OpenSSH 7.1p2: * SECURITY: ssh(1): The OpenSSH client code between 5.4 and 7.1 contains experimential support for resuming SSH-connections (roaming). The matching server code has never been shipped, but the client code was enabled by default and could be tricked by a malicious server into leaking client memory to the server, including private client user keys. The authentication of the server host key prevents exploitation by a man-in-the-middle, so this information leak is restricted to connections to malicious or compromised servers. MITIGATION: For OpenSSH >= 5.4 the vulnerable code in the client can be completely disabled by adding 'UseRoaming no' to the gobal ssh_config(5) file, or to user configuration in ~/.ssh/config, or by passing -oUseRoaming=no on the command line. PATCH: See below for a patch to disable this feature (Disabling Roaming in the Source Code). This problem was reported by the Qualys Security Advisory team. * SECURITY: Eliminate the fallback from untrusted X11-forwarding to trusted forwarding for cases when the X server disables the SECURITY extension. Reported by Thomas Hoger. * SECURITY: Fix an out of-bound read access in the packet handling code. Reported by Ben Hawkes. * PROTOCOL: Correctly interpret the 'first_kex_follows' option during the intial key exchange. Reported by Matt Johnston. * Further use of explicit_bzero has been added in various buffer handling code paths to guard against compilers aggressively doing dead-store removal. Potentially-incompatible changes: * This release disables a number of legacy cryptographic algorithms by default in ssh: + Several ciphers blowfish-cbc, cast128-cbc, all arcfour variants and the rijndael-cbc aliases for AES. + MD5-based and truncated HMAC algorithms. - OpenSSH 7.2: Security: * ssh(1), sshd(8): remove unfinished and unused roaming code (was already forcibly disabled in OpenSSH 7.1p2). * ssh(1): eliminate fallback from untrusted X11 forwarding to trusted forwarding when the X server disables the SECURITY extension. * ssh(1), sshd(8): increase the minimum modulus size supported for diffie-hellman-group-exchange to 2048 bits. * sshd(8): pre-auth sandboxing is now enabled by default (previous releases enabled it for new installations via sshd_config). New Features: * all: add support for RSA signatures using SHA-256/512 hash algorithms based on draft-rsa-dsa-sha2-256-03.txt and draft-ssh-ext-info-04.txt. * ssh(1): Add an AddKeysToAgent client option which can be set to 'yes', 'no', 'ask', or 'confirm', and defaults to 'no'. When enabled, a private key that is used during authentication will be added to ssh-agent if it is running (with confirmation enabled if set to 'confirm'). * sshd(8): add a new authorized_keys option "restrict" that includes all current and future key restrictions (no-*-forwarding, etc.). Also add permissive versions of the existing restrictions, e.g. "no-pty" -> "pty". This simplifies the task of setting up restricted keys and ensures they are maximally-restricted, regardless of any permissions we might implement in the future. * ssh(1): add ssh_config CertificateFile option to explicitly list certificates. bz#2436 * ssh-keygen(1): allow ssh-keygen to change the key comment for all supported formats. * ssh-keygen(1): allow fingerprinting from standard input, e.g. "ssh-keygen -lf -" * ssh-keygen(1): allow fingerprinting multiple public keys in a file, e.g. "ssh-keygen -lf ~/.ssh/authorized_keys" bz#1319 * sshd(8): support "none" as an argument for sshd_config Foreground and ChrootDirectory. Useful inside Match blocks to override a global default. bz#2486 * ssh-keygen(1): support multiple certificates (one per line) and reading from standard input (using "-f -") for "ssh-keygen -L" * ssh-keyscan(1): add "ssh-keyscan -c ..." flag to allow fetching certificates instead of plain keys. * ssh(1): better handle anchored FQDNs (e.g. 'cvs.openbsd.org') in hostname canonicalisation - treat them as already canonical and remove the trailing '.' before matching ssh_config. Bugfixes: * sftp(1): existing destination directories should not terminate recursive uploads (regression in openssh 6.8) * ssh(1), sshd(8): correctly send back SSH2_MSG_UNIMPLEMENTED replies to unexpected messages during key exchange. * ssh(1): refuse attempts to set ConnectionAttempts=0, which does not make sense and would cause ssh to print an uninitialised stack variable. * ssh(1): fix errors when attempting to connect to scoped IPv6 addresses with hostname canonicalisation enabled. * sshd_config(5): list a couple more options usable in Match blocks. * sshd(8): fix "PubkeyAcceptedKeyTypes +..." inside a Match block. * ssh(1): expand tilde characters in filenames passed to -i options before checking whether or not the identity file exists. Avoids confusion for cases where shell doesn't expand (e.g. "-i ~/file" vs. "-i~/file"). * ssh(1): do not prepend "exec" to the shell command run by "Match exec" in a config file, which could cause some commands to fail in certain environments. * ssh-keyscan(1): fix output for multiple hosts/addrs on one line when host hashing or a non standard port is in use * sshd(8): skip "Could not chdir to home directory" message when ChrootDirectory is active. * ssh(1): include PubkeyAcceptedKeyTypes in ssh -G config dump. * sshd(8): avoid changing TunnelForwarding device flags if they are already what is needed; makes it possible to use tun/tap networking as non-root user if device permissions and interface flags are pre-established * ssh(1), sshd(8): RekeyLimits could be exceeded by one packet. * ssh(1): fix multiplexing master failure to notice client exit. * ssh(1), ssh-agent(1): avoid fatal() for PKCS11 tokens that present empty key IDs. * sshd(8): avoid printf of NULL argument. * ssh(1), sshd(8): allow RekeyLimits larger than 4GB. * ssh-keygen(1): sshd(8): fix several bugs in (unused) KRL signature support. * ssh(1), sshd(8): fix connections with peers that use the key exchange guess feature of the protocol. * sshd(8): include remote port number in log messages. * ssh(1): don't try to load SSHv1 private key when compiled without SSHv1 support. * ssh-agent(1), ssh(1): fix incorrect error messages during key loading and signing errors. * ssh-keygen(1): don't leave empty temporary files when performing known_hosts file edits when known_hosts doesn't exist. * sshd(8): correct packet format for tcpip-forward replies for requests that don't allocate a port * ssh(1), sshd(8): fix possible hang on closed output. * ssh(1): expand %i in ControlPath to UID. * ssh(1), sshd(8): fix return type of openssh_RSA_verify. * ssh(1), sshd(8): fix some option parsing memory leaks. * ssh(1): add a some debug output before DNS resolution; it's a place where ssh could previously silently stall in cases of unresponsive DNS servers. * ssh(1): remove spurious newline in visual hostkey. * ssh(1): fix printing (ssh -G ...) of HostKeyAlgorithms=+... * ssh(1): fix expansion of HostkeyAlgorithms=+... Documentation: * ssh_config(5), sshd_config(5): update default algorithm lists to match current reality. * ssh(1): mention -Q key-plain and -Q key-cert query options. * sshd_config(8): more clearly describe what AuthorizedKeysFile=none does. * ssh_config(5): better document ExitOnForwardFailure. * sshd(5): mention internal DH-GEX fallback groups in manual. * sshd_config(5): better description for MaxSessions option. Portability: * sshd(8): fix multiple authentication using S/Key. - OpenSSH 7.2p2: Security: * sshd(8): sanitise X11 authentication credentials to avoid xauth command injection when X11Forwarding is enabled.

Tegan and Sara on Their Grammy-Nominated DVD 'Get Along'VOICE OVER: Rebecca Brayton
After growing up in Calgary, Alberta listening to the '70s bands their parents liked, the '80s bands everyone liked and the '90s bands punk rockers liked, twins Tegan and Sara decided they were ready to start creating their own sound. In this video, http://www.WatchMojo.com sits down with Sara of Tegan and Sara to discuss the duo's Grammy-nominated DVD "Get Along" and how shocked they were to be nominated. We also chat about the band's following and what has made them so loyal to the group. Finally, we move on to the topic of cover songs, where we learn about some of the girls' favorites and how they choose which songs to put their mark on. For more information, click Here.
