spice vulnerability

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

  • Ubuntu 18.10
  • Ubuntu 18.04 LTS
  • 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


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.
