"The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by a vulnerability as referenced
in the USN-3156-1 advisory.

    Jann Horn discovered that APT incorrectly handled InRelease files. If a remote attacker were able to
    perform a machine-in-the-middle attack, this flaw could potentially be used to install altered packages.

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
