"The remote Ubuntu 14.04 LTS host has packages installed that are affected by a vulnerability as referenced in the
USN-2961-1 advisory.

    It was discovered that a double free() could occur when the intent handling code in the Little CMS library
    detected an error. An attacker could use this to specially craft a file that caused an application using
    the Little CMS library to crash 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.");
