GNU Bash through 4.3 processes trailing strings after function definitions in the values of environment variables which allows remote attackers to execute arbitrary code via a crafted environment as demonstrated by vectors involving the ForceCommand feature in OpenSSH sshd the mod_cgi and mod_cgid modules in the Apache HTTP Server scripts executed by unspecified DHCP clients and other situations in which setting the environment occurs across a privilege boundary from Bash execution aka \ShellShock.\ NOTE: the original fix for this issue was incorrect; CVE-2014-7169 has been assigned to cover the vulnerability that is still present after the incorrect fix.
