Ubuntu Security Notice USN-2159-1
2nd April, 2014
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 13.10
- Ubuntu 12.10
- Ubuntu 12.04 LTS
- Ubuntu 10.04 LTS
NSS could be made to expose sensitive information over the network.
- nss - Network Security Service library
It was discovered that NSS incorrectly handled wildcard certificates when
used with internationalized domain names. If a remote attacker were able to
perform a man-in-the-middle attack, this flaw could be exploited to spoof
The problem can be corrected by updating your system to the following package version:
- Ubuntu 13.10:
- libnss3 2:3.15.4-0ubuntu0.13.10.2
- Ubuntu 12.10:
- libnss3 3.15.4-0ubuntu0.12.10.2
- Ubuntu 12.04 LTS:
- libnss3 3.15.4-0ubuntu0.12.04.2
- Ubuntu 10.04 LTS:
- libnss3-1d 3.15.4-0ubuntu0.10.04.2
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.
