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.

zhangyang reports :

The ReadFrame function in the avi.c file uses a variable i_width_bytes, which is obtained directly from the file. It is a signed integer. It does not do a strict check before the memory operation(memmove, memcpy), which may cause a buffer overflow.

The version of VLC media player installed on the remote host is earlier than 3.0.7.  It is, therefore, affected by multiple vulnerabilities:

  - A heap-based buffer overflow condition exists in ReadFrame     due to improper parsing of AVI files. A remote attacker can     exploit this by tricking a user into opening a specially     crafted avi file to cause a denial of service condition     or the execution of arbitrary code.(CVE-2019-5439)

  - A double free vulnerability exists in zlib_decompress_extra     due to improper parsing of MKV files. A remote attacker can     exploit this by tricking a user into opening a specially     crafted MKV file to cause a denial of service condition     or the execution of arbitrary code.(CVE-2019-12874)

  - An Integer underflow in VLC Media Player versions < 3.0.7     leads to an out-of-band read..(CVE-2019-5459)

  - A double free vulnerability exists which lead to VLC application to crash.
    (CVE-2019-5460)

The remote host is affected by the vulnerability described in GLSA-201908-23 (VLC: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in VLC. Please review the       CVE identifiers referenced below for details.
  Impact :

    Remote attackers, by enticing a user to execute a specially crafted       media file, could cause a Denial of Service condition or possibly execute       arbitrary code.
  Workaround :

    There is no known workaround at this time.
