The remote Ubuntu 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4074-1 advisory.

    It was discovered that the VLC CAF demuxer incorrectly handled certain files. If a user were tricked into     opening a specially-crafted CAF file, a remote attacker could use this issue to cause VLC to crash,     resulting in a denial of service. This issue only affected Ubuntu 18.04 LTS. (CVE-2018-19857)

    It was discovered that the VLC Matroska demuxer incorrectly handled certain files. If a user were tricked     into opening a specially-crafted MKV file, a remote attacker could use this issue to cause VLC to crash,     resulting in a denial of service, or possibly execute arbitrary code. (CVE-2019-12874)

    It was discovered that the VLC MP4 demuxer incorrectly handled certain files. If a user were tricked into     opening a specially-crafted MP4 file, a remote attacker could use this issue to cause VLC to crash,     resulting in a denial of service, or possibly execute arbitrary code. (CVE-2019-13602)

    It was discovered that the VLC AVI demuxer incorrectly handled certain files. If a user were tricked into     opening a specially-crafted AVI file, a remote attacker could use this issue to cause VLC to crash,     resulting in a denial of service, or possibly execute arbitrary code. (CVE-2019-5439)

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 number.

The version of VLC media player installed on the remote host with version 3.0.4.  It is, therefore, affected by a denial of service and/or a potential infoleak vulnerability. (CVE-2018-19857).

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - The CAF demuxer in modules/demux/caf.c in VideoLAN VLC media player 3.0.4 may read memory from an     uninitialized pointer when processing magic cookies in CAF files, because a ReadKukiChunk() cast converts     a return value to an unsigned int even if that value is negative. This could result in a denial of service     and/or a potential infoleak. (CVE-2018-19857)

Note that Nessus relies on the presence of the package as reported by the vendor.
