==========================================================================

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

Summary:

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

Details:

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.
