This vulnerability appears to have been fixed in     9807d3976be0e92e4ece3b4b1701be894cd7c2e1 and later. (CVE-2018-1999012)

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

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

  - FFmpeg before commit cced03dd667a5df6df8fd40d8de0bff477ee02e8 contains multiple out of array access
    vulnerabilities in the mms protocol that can result in attackers accessing out of bound data. This attack
    appear to be exploitable via network connectivity. This vulnerability appears to have been fixed in
    cced03dd667a5df6df8fd40d8de0bff477ee02e8 and later. (CVE-2018-1999010)

  - In FFmpeg 4.0.1, due to a missing check of a profile value before setting it, the
    ff_mpeg4_decode_picture_header function in libavcodec/mpeg4videodec.c may trigger a NULL pointer
    dereference while converting a crafted AVI file to MPEG4, leading to a denial of service. (CVE-2018-13301)

  - In FFmpeg 4.0.1, a missing check for failure of a call to init_get_bits8() in the avpriv_ac3_parse_header
    function in libavcodec/ac3_parser.c may trigger a NULL pointer dereference while converting a crafted AVI
    file to MPEG4, leading to a denial of service. (CVE-2018-13303)

  - In libavcodec in FFmpeg 4.0.1, improper maintenance of the consistency between the context profile field
    and studio_profile in libavcodec may trigger an assertion failure while converting a crafted AVI file to
    MPEG4, leading to a denial of service, related to error_resilience.c, h263dec.c, and mpeg4videodec.c.
    (CVE-2018-13304)

Several security issues have been corrected in multiple demuxers and decoders of the libav multimedia library.

CVE-2015-1872

The ff_mjpeg_decode_sof function in libavcodec/mjpegdec.c did not validate the number of components in a JPEG-LS Start Of Frame segment, which allowed remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted Motion JPEG data.

CVE-2017-14058

The read_data function in libavformat/hls.c did not restrict reload attempts for an insufficient list, which allowed remote attackers to cause a denial of service (infinite loop).

CVE-2017-1000460

In get_last_needed_nal() (libavformat/h264.c) the return value of init_get_bits was ignored and get_ue_golomb(&gb) was called on an uninitialized get_bits context, which caused a NULL deref exception.

CVE-2018-6392

The filter_slice function in libavfilter/vf_transpose.c allowed remote attackers to cause a denial of service (out-of-array access) via a crafted MP4 file.

CVE-2018-1999012

libav contained a CWE-835: Infinite loop vulnerability in pva format demuxer that could result in a vulnerability that allowed attackers to consume excessive amount of resources like CPU and RAM. This attack appeared to be exploitable via specially crafted PVA file had to be provided as input.

For Debian 8 'Jessie', these problems have been fixed in version 6:11.12-1~deb8u6.

We recommend that you upgrade your libav packages.
