The studio profile decoder in libavcodec/mpeg4videodec.c in FFmpeg 4.0 before 4.0.4 and 4.1 before 4.1.2 allows remote attackers to cause a denial of service (out-of-array access) or possibly have unspecified other impact via crafted MPEG-4 video data.

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - In FFmpeg 3.2 and 4.1, a denial of service in the subtitle decoder allows attackers to hog the CPU via a
    crafted video file in Matroska format, because ff_htmlmarkup_to_ass in libavcodec/htmlsubtitles.c has a
    complex format argument to sscanf. (CVE-2019-9718)

  - A denial of service in the subtitle decoder in FFmpeg 3.2 and 4.1 allows attackers to hog the CPU via a
    crafted video file in Matroska format, because handle_open_brace in libavcodec/htmlsubtitles.c has a
    complex format argument to sscanf. (CVE-2019-9721)

  - libavcodec/hevcdec.c in FFmpeg 3.4 and 4.1.2 mishandles detection of duplicate first slices, which allows
    remote attackers to cause a denial of service (NULL pointer dereference and out-of-array access) or
    possibly have unspecified other impact via crafted HEVC data. (CVE-2019-11338)

  - The studio profile decoder in libavcodec/mpeg4videodec.c in FFmpeg 4.0 before 4.0.4 and 4.1 before 4.1.2
    allows remote attackers to cause a denial of service (out-of-array access) or possibly have unspecified
    other impact via crafted MPEG-4 video data. (CVE-2019-11339)

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - The flv_write_packet function in libavformat/flvenc.c in FFmpeg through 2.8 does not check for an empty
    audio packet, leading to an assertion failure. (CVE-2018-15822)

  - In FFmpeg 3.2 and 4.1, a denial of service in the subtitle decoder allows attackers to hog the CPU via a
    crafted video file in Matroska format, because ff_htmlmarkup_to_ass in libavcodec/htmlsubtitles.c has a
    complex format argument to sscanf. (CVE-2019-9718)

  - A denial of service in the subtitle decoder in FFmpeg 3.2 and 4.1 allows attackers to hog the CPU via a
    crafted video file in Matroska format, because handle_open_brace in libavcodec/htmlsubtitles.c has a
    complex format argument to sscanf. (CVE-2019-9721)

  - The studio profile decoder in libavcodec/mpeg4videodec.c in FFmpeg 4.0 before 4.0.4 and 4.1 before 4.1.2
    allows remote attackers to cause a denial of service (out-of-array access) or possibly have unspecified
    other impact via crafted MPEG-4 video data. (CVE-2019-11339)

The remote Ubuntu 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3967-1 advisory.

    It was discovered that FFmpeg contained multiple security issues when handling certain multimedia files.
    If a user were tricked into opening a crafted multimedia file, an attacker could cause a denial of service     via application crash.

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.
