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

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

- Ubuntu 16.10
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS

Summary:

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

Software Description:
- spice: SPICE protocol client and server library

Details:

Frediano Ziglio discovered that Spice incorrectly handled certain client
messages. A remote attacker could use this issue to cause Spice 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 16.10:
  libspice-server1                0.12.8-1ubuntu0.1

Ubuntu 16.04 LTS:

After a standard system update you need to restart qemu guests to make
all the necessary changes.
