openssl update
=========================================================================
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.
