Unspecified vulnerability in the Java Runtime Environment (JRE) component in Oracle Java SE 7 through Update 11 6 through Update 38 5.0 through Update 38 and 1.4.2_40 and earlier and OpenJDK 6 and 7 allows remote attackers to affect confidentiality and integrity via vectors related to JSSE. NOTE: the previous information is from the February 2013 CPU. Oracle has not commented on claims from another vendor that this issue is related to incorrect validation of Diffie-Hellman keys which allows remote attackers to conduct a \small subgroup attack\ to force the use of weak session keys or obtain sensitive information about the private key.
