==========================================================================
Ubuntu Security Notice USN-2863-1
January 07, 2016

openssl vulnerability
==========================================================================

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

- Ubuntu 12.04 LTS

Summary:

OpenSSL could be made to expose sensitive information over the network.

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

Details:

Karthikeyan Bhargavan and Gaetan Leurent discovered that OpenSSL
incorrectly allowed MD5 to be used for TLS 1.2 connections. If a remote
attacker were able to perform a man-in-the-middle attack, this flaw could
be exploited to view sensitive information.

Update instructions:

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

Ubuntu 12.04 LTS:
  libssl1.0.0                     1.0.1-4ubuntu5.33

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