Ubuntu Security Notice USN-2865-1
January 08, 2016

gnutls26, gnutls28 vulnerability
==========================================================================

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

– Ubuntu 15.04
– Ubuntu 14.04 LTS
– Ubuntu 12.04 LTS

Summary:

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

Software Description:
– gnutls28: GNU TLS library
– gnutls26: GNU TLS library

Details:

Karthikeyan Bhargavan and Gaetan Leurent discovered that GnuTLS 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 15.04:
libgnutls-deb0-28 3.3.8-3ubuntu3.2
libgnutls-openssl27 3.3.8-3ubuntu3.2
libgnutlsxx28 3.3.8-3ubuntu3.2

Ubuntu 14.04 LTS:
libgnutls-openssl27 2.12.23-12ubuntu2.4
libgnutls26 2.12.23-12ubuntu2.4
libgnutlsxx27 2.12.23-12ubuntu2.4

Ubuntu 12.04 LTS:
libgnutls-openssl27 2.12.14-5ubuntu3.11
libgnutls26 2.12.14-5ubuntu3.11
libgnutlsxx27 2.12.14-5ubuntu3.11

In general, a standard system update will make all the necessary changes.
