USN-2027-1: SPICE vulnerability
Ubuntu Security Notice USN-2027-1
12th November, 2013
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 13.10
- Ubuntu 13.04
SPICE could be made to crash if it received specially crafted network traffic.
- spice - SPICE protocol client and server library
Tomas Jamrisko discovered that SPICE incorrectly handled long passwords in
SPICE tickets. An attacker could use this issue to cause the SPICE server
to crash, resulting in a denial of service.
The problem can be corrected by updating your system to the following package version:
- Ubuntu 13.10:
- libspice-server1 0.12.4-0nocelt1ubuntu0.1
- Ubuntu 13.04:
- libspice-server1 0.12.2-0nocelt2expubuntu1.2
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
After a standard system update you need to restart applications using the
SPICE protocol, such as QEMU, to make all the necessary changes.
