USN-2606-1: OpenSSL update
12 May 2015
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.04 LTS
OpenSSL TLSv1.2 client support has been enabled in Ubuntu 12.04 LTS.
- openssl - Secure Socket Layer (SSL) cryptographic library and tools
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.
The problem can be corrected by updating your system to the following package versions:
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
After a standard system update you need to reboot your computer to make all the necessary changes.
