USN-3355-1: Spice vulnerability

19 July 2017

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



  • 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
Ubuntu 16.04
Ubuntu 14.04

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