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

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

- Ubuntu 14.10
- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS
- Ubuntu 10.04 LTS

Summary:

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

Software Description:
- nss: Network Security Service library

Details:

It was discovered that NSS incorrectly handled certain ASN.1 lengths. A
remote attacker could possibly use this issue to perform a data-smuggling
attack.

Update instructions:

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

Ubuntu 14.10:
  libnss3                         2:3.17.1-0ubuntu1.1

Ubuntu 14.04 LTS:
  libnss3                         2:3.17.1-0ubuntu0.14.04.2

Ubuntu 12.04 LTS:
  libnss3                         3.17.1-0ubuntu0.12.04.2

Ubuntu 10.04 LTS:
  libnss3-1d                      3.17.1-0ubuntu0.10.04.2

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.
