Ubuntu Security Notice USN-2159-1
April 02, 2014

nss vulnerability

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

- Ubuntu 13.10
- Ubuntu 12.10
- Ubuntu 12.04 LTS
- Ubuntu 10.04 LTS


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

Software Description:
- nss: Network Security Service library


It was discovered that NSS incorrectly handled wildcard certificates when
used with internationalized domain names. If a remote attacker were able to
perform a man-in-the-middle attack, this flaw could be exploited to spoof
SSL servers.

Update instructions:

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

Ubuntu 13.10:
  libnss3                         2:3.15.4-0ubuntu0.13.10.2

Ubuntu 12.10:
  libnss3                         3.15.4-0ubuntu0.12.10.2

Ubuntu 12.04 LTS:
  libnss3                         3.15.4-0ubuntu0.12.04.2

Ubuntu 10.04 LTS:
  libnss3-1d                      3.15.4-0ubuntu0.10.04.2

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.
