USN-2088-1: NSS vulnerability

23 January 2014

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



  • nss - Network Security Service library


Brian Smith discovered that NSS incorrectly handled the TLS False Start
feature. If a remote attacker were able to perform a machine-in-the-middle
attack, this flaw could be exploited to spoof SSL servers.

Update instructions

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

Ubuntu 13.10
Ubuntu 12.10
Ubuntu 12.04
Ubuntu 10.04

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.
