"The remote Ubuntu 16.04 ESM host has packages installed that are affected by a vulnerability as referenced in the
USN-5656-1 advisory.

  - posix/JackSocket.cpp in libjack in JACK2 1.9.1 through 1.9.12 (as distributed with alsa-plugins 1.1.7 and
    later) has a double file descriptor close issue during a failed connection attempt when jackd2 is not
    running. Exploitation success depends on multithreaded timing of that double close, which can result in
    unintended information disclosure, crashes, or file corruption due to having the wrong file associated
    with the file descriptor. (CVE-2019-13351)

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