Ubuntu Security Notice USN-2864-1
January 07, 2016

nss vulnerability
==========================================================================

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

- Ubuntu 15.10
- Ubuntu 15.04
- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS

Summary:

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

Software Description:
- nss: Network Security Service library

Details:

Karthikeyan Bhargavan and Gaetan Leurent discovered that NSS 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 15.10:
libnss3 2:3.19.2.1-0ubuntu0.15.10.2

Ubuntu 15.04:
libnss3 2:3.19.2.1-0ubuntu0.15.04.2

Ubuntu 14.04 LTS:
libnss3 2:3.19.2.1-0ubuntu0.14.04.2

Ubuntu 12.04 LTS:
libnss3 3.19.2.1-0ubuntu0.12.04.2

After a standard system update you need to restart any applications that
use NSS, such as Evolution and Chromium, to make all the necessary changes.
