30th September, 2013
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 13.04
- Ubuntu 12.10

Vino could be made to hang if it received specially crafted network traffic.

Jonathan Claudius discovered that Vino incorrectly handled closing invalid
connections. A remote attacker could use this issue to cause Vino to
consume resources, resulting in a denial of service.
The problem can be corrected by updating your system to the following package version:

- vino 3.6.2-0ubuntu4.1

- vino 3.6.0-0ubuntu1.2

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