nss vulnerability
=========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS
- Ubuntu 10.04 LTS
Summary:
NSS could be made to crash or run programs as your login if it processed a
specially crafted certificate.
Software Description:
- nss: Network Security Service library
Details:
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 LTS:
libnss3 2:3.15.4-1ubuntu7.1
Ubuntu 12.04 LTS:

Ubuntu 10.04 LTS:
libnss3-1d 3.15.4-0ubuntu0.10.04.3
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.
