6 October 2020
Spice could be made to crash or run programs if it received specially crafted network traffic.
Releases
Packages
- spice - SPICE protocol client and server library
Details
Frediano Ziglio discovered that Spice incorrectly handled QUIC image
decoding. 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 20.04
Ubuntu 18.04
Ubuntu 16.04
After a standard system update you need to restart qemu guests to make all
the necessary changes.
