USN-2343-1: NSS vulnerability

09 September 2014

NSS could be made to crash or run programs as your login if it processed a specially crafted certificate.



  • nss - Network Security Service library


Tyson Smith and Jesse Schwartzentruber discovered that NSS contained a race
condition when performing certificate validation. An attacker could use
this issue to cause NSS to crash, resulting in a denial of service, or
possibly execute arbitrary code.

Update instructions

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

Ubuntu 14.04
Ubuntu 12.04
Ubuntu 10.04

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.
