USN-2606-1: OpenSSL update

Releases

• Ubuntu 12.04

Packages

• 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

• 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.
