The sdp_parse_fmtp_config_h264 function in libavformat/rtpdec_h264.c in FFmpeg before 3.3.4 mishandles empty sprop-parameter-sets values, which allows remote attackers to cause a denial of service (heap buffer overflow) or possibly have unspecified other impact via a crafted sdp file.

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

  - The sdp_parse_fmtp_config_h264 function in libavformat/rtpdec_h264.c in FFmpeg before 3.3.4 mishandles
    empty sprop-parameter-sets values, which allows remote attackers to cause a denial of service (heap buffer
    overflow) or possibly have unspecified other impact via a crafted sdp file. (CVE-2017-14767)

  - In libavformat/rmdec.c in FFmpeg 3.3.3, a DoS in ivr_read_header() due to lack of an EOF (End of File)
    check might cause huge CPU consumption. When a crafted IVR file, which claims a large "len" field in the
    header but does not contain sufficient backing data, is provided, the first type==4 loop would consume
    huge CPU resources, since there is no EOF check inside the loop. (CVE-2017-14054)

  - In libavformat/mvdec.c in FFmpeg 3.3.3, a DoS in mv_read_header() due to lack of an EOF (End of File)
    check might cause huge CPU and memory consumption. When a crafted MV file, which claims a large
    "nb_frames" field in the header but does not contain sufficient backing data, is provided, the loop over
    the frames would consume huge CPU and memory resources, since there is no EOF check inside the loop.
    (CVE-2017-14055)

  - In libavformat/rl2.c in FFmpeg 3.3.3, a DoS in rl2_read_header() due to lack of an EOF (End of File) check
    might cause huge CPU and memory consumption. When a crafted RL2 file, which claims a large "frame_count"
    field in the header but does not contain sufficient backing data, is provided, the loops (for offset and
    size tables) would consume huge CPU and memory resources, since there is no EOF check inside these loops.
    (CVE-2017-14056)

  - In FFmpeg 3.3.3, a DoS in asf_read_marker() due to lack of an EOF (End of File) check might cause huge CPU
    and memory consumption. When a crafted ASF file, which claims a large "name_len" or "count" field in the
    header but does not contain sufficient backing data, is provided, the loops over the name and markers
    would consume huge CPU and memory resources, since there is no EOF check inside these loops.
    (CVE-2017-14057)

Several security vulnerabilities were corrected in the libav multimedia library which may lead to a denial of service, information disclosure or the execution of arbitrary code if a malformed file is processed.

CVE-2017-9993

Libav does not properly restrict HTTP Live Streaming filename extensions and demuxer names, which allows attackers to read arbitrary files via crafted playlist data.

CVE-2017-9994

libavcodec/webp.c in Libav does not ensure that pix_fmt is set, which allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted file, related to the vp8_decode_mb_row_no_filter and pred8x8_128_dc_8_c functions.

CVE-2017-14055

denial of service in mv_read_header() due to lack of an EOF (End of File) check might cause huge CPU and memory consumption.

CVE-2017-14056

denial of service in rl2_read_header() due to lack of an EOF (End of File) check might cause huge CPU and memory consumption.

CVE-2017-14057

denial of service in asf_read_marker() due to lack of an EOF (End of File) check might cause huge CPU and memory consumption.

CVE-2017-14170

denial of service in mxf_read_index_entry_array() due to lack of an EOF (End of File) check might cause huge CPU consumption.

CVE-2017-14171

denial of service in nsv_parse_NSVf_header() due to lack of an EOF (End of File) check might cause huge CPU consumption.

CVE-2017-14767

The sdp_parse_fmtp_config_h264 function in libavformat/rtpdec_h264.c mishandles empty sprop-parameter-sets values, which allows remote attackers to cause a denial of service (heap buffer overflow) or possibly have unspecified other impact via a crafted sdp file.

CVE-2017-15672

The read_header function in libavcodec/ffv1dec.c allows remote attackers to have unspecified impact via a crafted MP4 file, which triggers an out-of-bounds read.

CVE-2017-17130

The ff_free_picture_tables function in libavcodec/mpegpicture.c allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted file, related to vc1_decode_i_blocks_adv.

CVE-2018-6621

The decode_frame function in libavcodec/utvideodec.c in Libav allows remote attackers to cause a denial of service (out of array read) via a crafted AVI file.

CVE-2018-7557

The decode_init function in libavcodec/utvideodec.c in Libav allows remote attackers to cause a denial of service (Out of array read) via an AVI file with crafted dimensions within chroma subsampling data.

CVE-2018-14394

libavformat/movenc.c in Libav allows attackers to cause a denial of service (application crash caused by a divide-by-zero error) with a user crafted Waveform audio file.

CVE-2018-1999010

Libav contains multiple out of array access vulnerabilities in the mms protocol that can result in attackers accessing out of bound data.

For Debian 8 'Jessie', these problems have been fixed in version 6:11.12-1~deb8u4.

We recommend that you upgrade your libav packages.
