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

  - In FFmpeg 4.0.1, improper handling of frame types (other than EAC3_FRAME_TYPE_INDEPENDENT) that have
    multiple independent substreams in the handle_eac3 function in libavformat/movenc.c may trigger an out-of-
    array access while converting a crafted AVI file to MPEG4, leading to a denial of service or possibly
    unspecified other impact. (CVE-2018-13302)

  - The decode_init function in libavcodec/utvideodec.c in FFmpeg 2.8 through 3.4.2 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-2018-7557)

  - The svg_probe function in libavformat/img2dec.c in FFmpeg through 3.4.2 allows remote attackers to cause a
    denial of service (Infinite Loop) via a crafted XML file. (CVE-2018-7751)

  - The decode_init function in libavcodec/utvideodec.c in FFmpeg through 3.4.2 allows remote attackers to
    cause a denial of service (out of array read) via an AVI file. (CVE-2018-10001)

  - An improper integer type in the mpeg4_encode_gop_header function in libavcodec/mpeg4videoenc.c in FFmpeg
    2.8 and 4.0 may trigger an assertion violation while converting a crafted AVI file to MPEG4, leading to a
    denial of service. (CVE-2018-12458)

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.

This update for ffmpeg fixes the following issues :

CVE-2018-13300: An improper argument passed to the avpriv_request_sample function may have triggered an out-of-array read while converting a crafted AVI file to MPEG4, leading to a denial of service and possibly an information disclosure (bsc#1100348)

CVE-2018-15822: The flv_write_packet function did not check for an empty audio packet, leading to an assertion failure and DoS (bsc#1105869)

CVE-2018-13305: Due to a missing check for negative values of the mquant variable, the vc1_put_blocks_clamped function in libavcodec/vc1_block.c may trigger an out-of-array access while converting a crafted AVI file to MPEG4, leading to an information disclosure or a denial of service. (bsc#1100345).

CVE-2018-12458: An improper integer type in the mpeg4_encode_gop_header function in libavcodec/mpeg4videoenc.c might have triggered an assertion violation while converting a crafted AVI file to MPEG4, leading to a denial of service. (bsc#1097983).
