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

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

Summary:

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

Software Description:

Details:

Frediano Ziglio discovered that Spice incorrectly handled certain invalid
monitor configurations. A remote attacker could use this issue to cause
Spice 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 versions:
