  • spice - SPICE protocol client and server library

Details

Christophe Fergeau discovered that Spice incorrectly handled memory. A
remote attacker could use this 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 18.10
Ubuntu 18.04
Ubuntu 16.04
Ubuntu 14.04

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