FFmpeg before commit 2b46ebdbff1d8dec7a3d8ea280a612b91a582869 contains a Buffer Overflow vulnerability in asf_o format demuxer that can result in heap-buffer-overflow that may result in remote code execution. This attack appears to be exploitable via specially crafted ASF file that has to be provided as input to FFmpeg. This vulnerability appears to have been fixed in 2b46ebdbff1d8dec7a3d8ea280a612b91a582869 and later.

  - 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 vulnerabilities have been discovered in the FFmpeg multimedia framework, which could result in denial of service or potentially the execution of arbitrary code if malformed files/streams are processed.
