Ubuntu 12.04 LTS : openssl update (USN-2367-1)
High Nessus Plugin ID 78040
SynopsisThe remote Ubuntu host is missing a security-related patch.
DescriptionFor compatibility reasons, OpenSSL in Ubuntu 12.04 LTS disables TLSv1.2 by default when being used as a client. When forcing the use of TLSv1.2, another compatibility feature (OPENSSL_MAX_TLS1_2_CIPHER_LENGTH) was used that would truncate the cipher list. This would prevent certain ciphers from being selected, and would prevent secure renegotiations. This update removes the cipher list truncation workaround when forcing the use of TLSv1.2.
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpdate the affected libssl1.0.0 package.
