"The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as
referenced in the USN-3602-1 advisory.

    It was discovered that LibTIFF incorrectly handled certain malformed images. If a user or automated system
    were tricked into opening a specially crafted image, a remote attacker could crash the application,
    leading to a denial of service, or possibly execute arbitrary code with user privileges.

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

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
