USN-2101-1: libgadu vulnerability

10 February 2014

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.

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

After a standard system update you need to restart your session to make all
the necessary changes.
