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.

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

  - 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)

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.
