Ubuntu Security Notice USN-2101-1
10th February, 2014
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 13.10
- Ubuntu 12.10
- Ubuntu 12.04 LTS
libgadu could be made to crash or run programs if it received specially crafted network traffic.
- libgadu - Gadu-Gadu protocol library
Yves Younan and Ryan Pentney discovered that libgadu incorrectly handled
certain Gadu-Gadu HTTP messages. A malicious remote server or a man in the
middle could use this issue to cause applications using libgadu to crash,
resulting in a denial of service, or possibly execute arbitrary code.
The problem can be corrected by updating your system to the following package version:
- Ubuntu 13.10:
- libgadu3 1:1.11.2-1ubuntu1.1
- Ubuntu 12.10:
- libgadu3 1:1.11.2-1ubuntu0.12.10.1
- Ubuntu 12.04 LTS:
- libgadu3 1:1.11.1-1ubuntu0.1
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
After a standard system update you need to restart your session to make all
the necessary changes.
