Ubuntu Security Notice USN-2063-1
December 20, 2013

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

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

- Ubuntu 13.10
- Ubuntu 13.04
- Ubuntu 12.10
- Ubuntu 12.04 LTS
- Ubuntu 10.04 LTS

Summary:

Fraudulent security certificates could allow sensitive information to
be exposed when accessing the Internet.

Software Description:
- nss: Network Security Service library

Details:

It was discovered that an intermediate certificate was incorrectly issued
by a subordinate certificate authority of a trusted CA included in NSS.
This intermediate certificate could be used in a man-in-the-middle attack,
and has such been marked as untrusted in this update.

Update instructions:

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

Ubuntu 13.10:
libnss3 2:3.15.3.1-0ubuntu0.13.10.1

Ubuntu 13.04:
libnss3 2:3.15.3.1-0ubuntu0.13.04.1

Ubuntu 12.10:
libnss3 3.15.3.1-0ubuntu0.12.10.1

Ubuntu 12.04 LTS:
libnss3 3.15.3.1-0ubuntu0.12.04.1

Ubuntu 10.04 LTS:
libnss3-1d 3.15.3.1-0ubuntu0.10.04.1

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.
