nss vulnerabilities
=========================================================================
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 crash or run programs if it received specially
crafted input.

Software Description:
- nss: Network Security Service library

Details:

Tyson Smith and David Keeler discovered that NSS incorrectly handled
decoding certain ASN.1 data. An remote 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 15.10:
  libnss3                         2:3.19.2.1-0ubuntu0.15.10.1

Ubuntu 15.04:
  libnss3                         2:3.19.2.1-0ubuntu0.15.04.1

Ubuntu 14.04 LTS:
  libnss3                         2:3.19.2.1-0ubuntu0.14.04.1

Ubuntu 12.04 LTS:
  libnss3                         3.19.2.1-0ubuntu0.12.04.1

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.
