"The remote Ubuntu 14.04 LTS host has packages installed that are affected by a vulnerability as referenced in the
USN-2520-1 advisory.

    Peter De Wachter discovered that CUPS incorrectly handled certain malformed compressed raster files. A
    remote attacker could use this issue to cause CUPS to crash, resulting in a denial of service, or possibly
    execute arbitrary code.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
