    spice, spice-protocol vulnerability
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 18.04 LTS
    - Ubuntu 17.10
    - Ubuntu 16.04 LTS
    - Ubuntu 14.04 LTS
    
    Summary:
    
    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
    - spice-protocol: SPICE protocol headers
    
    Details:
    
    Frediano Ziglio discovered that Spice incorrectly handled certain
    client messages. An attacker could possibly 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 18.04 LTS:
      libspice-server1                0.14.0-1ubuntu2.1
    
    Ubuntu 17.10:

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