Ubuntu 12.04 LTS : openssl update (USN-2606-1)

High Nessus Plugin ID 83413


The remote Ubuntu host is missing a security-related patch.


For compatibility reasons, Ubuntu 12.04 LTS shipped OpenSSL with TLSv1.2 disabled when being used as a client.

This update re-enables TLSv1.2 by default now that the majority of problematic sites have been updated to fix compatibility issues.

For problematic environments, TLSv1.2 can be disabled again by setting the OPENSSL_NO_CLIENT_TLS1_2 environment variable before library initialization.

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.


Update the affected libssl1.0.0 package.
