Detail

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 12.04 LTS

Summary:

OpenSSL TLSv1.2 client support has been enabled in Ubuntu 12.04 LTS.

Software Description: - openssl: Secure Socket Layer (SSL) cryptographic library and tools

Details:

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.

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 12.04 LTS:
libssl1.0.0 1.0.1-4ubuntu5.27

After a standard system update you need to reboot your computer to make all the necessary changes.
