Ubuntu Security Notice USN-2606-1
May 12, 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
The problem can be corrected by updating your system to the following
Ubuntu 12.04 LTS:
After a standard system update you need to reboot your computer to make
all the necessary changes.
