Ubuntu Security Notice USN-3355-1
July 19, 2017

spice vulnerability

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

- Ubuntu 17.04
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS


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


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.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 17.04:
  libspice-server1                0.12.8-2ubuntu1.1

Ubuntu 16.04 LTS:
  libspice-server1                0.12.6-4ubuntu0.3

Ubuntu 14.04 LTS:
  libspice-server1                0.12.4-0nocelt2ubuntu1.5

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