========================================================================== 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.
