20th December, 2013
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
Fraudulent security certificates could allow sensitive information to be exposed when accessing the Internet.
- nss - Network Security Service library
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.
The problem can be corrected by updating your system to the following package version:
- Ubuntu 13.10:
- libnss3 2:220.127.116.11-0ubuntu0.13.10.1
- Ubuntu 13.04:
- libnss3 2:18.104.22.168-0ubuntu0.13.04.1
- Ubuntu 12.10:
- libnss3 22.214.171.124-0ubuntu0.12.10.1
- Ubuntu 12.04 LTS:
- libnss3 126.96.36.199-0ubuntu0.12.04.1
- Ubuntu 10.04 LTS:
- libnss3-1d 188.8.131.52-0ubuntu0.10.04.1
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
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.
