"The remote Debian 10 / 11 host has packages installed that are affected by a vulnerability as referenced in the dsa-5165
advisory.

    Multiple vulnerabilities were discovered in the VLC media player, which could result in the execution of
    arbitrary code or denial of service if a malformed file is opened. For the oldstable distribution
    (buster), this problem has been fixed in version 3.0.17.4-0+deb10u1. For the stable distribution
    (bullseye), this problem has been fixed in version 3.0.17.4-0+deb11u1. We recommend that you upgrade your
    vlc packages. For the detailed security status of vlc please refer to its security tracker page at:
    https://security-tracker.debian.org/tracker/vlc

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

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