Details

USN-1763-1 fixed a vulnerability in NSS. This update provides the NSPR
needed to use the new NSS.

Original advisory details:

Nadhem Alfardan and Kenny Paterson discovered that the TLS protocol as used
in NSS was vulnerable to a timing side-channel attack known as the
"Lucky Thirteen" issue. A remote attacker could use this issue to perform
plaintext-recovery attacks via analysis of timing data.

Update instructions

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

Ubuntu 12.10
Ubuntu 12.04
Ubuntu 11.10
Ubuntu 10.04

After a standard system update you need to restart any applications that
use NSPR, such as Evolution and Chromium, to make all the necessary changes.
