libavformat/movenc.c in FFmpeg before 4.0.2 allows attackers to cause a denial of service (application crash caused by a divide-by-zero error) with a user crafted Waveform audio file.

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

  - libavformat/movenc.c in FFmpeg before 4.0.2 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-2018-14394)

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:

  - 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)

This update for ffmpeg fixes the following issues :

Security issue fixed :

CVE-2018-14395: Fixed a divide-by-zero error in libavformat/movenc.c that allowed attackers to cause a DoS (bsc#1101889)

CVE-2018-14394: Fixed a divide-by-zero error in libavformat/movenc.c that allowed attackers to cause a DoS (bsc#1101888).

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

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.
