libgadu vulnerability
=========================================================================
A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 13.10
- Ubuntu 12.10
- Ubuntu 12.04 LTS

Summary:

libgadu could be made to crash or run programs if it received specially
crafted network traffic.

Software Description:
- libgadu: Gadu-Gadu protocol library

Details:

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:
  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
