The remote host is affected by the vulnerability described in GLSA-201603-06 (FFmpeg: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in FFmpeg.  Please review       the CVE identifiers referenced below for details.
  Impact :

    A remote attacker could possibly execute arbitrary code or cause a       Denial of Service condition.
  Workaround :

    There is no known workaround at this time.

Several security issues have been corrected in multiple demuxers and decoders of the libav multimedia library.

CVE-2014-8542

libavcodec/utils.c omitted a certain codec ID during enforcement of alignment, which allowed remote attackers to cause a denial of ervice (out-of-bounds access) or possibly have unspecified other impact via crafted JV data.

CVE-2015-1207

Double-free vulnerability in libavformat/mov.c allowed remote attackers to cause a denial of service (memory corruption and crash) via a crafted .m4a file.

CVE-2017-7863

libav had an out-of-bounds write caused by a heap-based buffer overflow related to the decode_frame_common function in libavcodec/pngdec.c.

CVE-2017-7865

libav had an out-of-bounds write caused by a heap-based buffer overflow related to the ipvideo_decode_block_opcode_0xA function in libavcodec/interplayvideo.c and the avcodec_align_dimensions2 function in libavcodec/utils.c.

CVE-2017-14169

In the mxf_read_primer_pack function in libavformat/mxfdec.c in, an integer signedness error might have occured when a crafted file, claiming a large 'item_num' field such as 0xffffffff, was provided. As a result, the variable 'item_num' turned negative, bypassing the check for a large value.

CVE-2017-14223

In libavformat/asfdec_f.c a DoS in asf_build_simple_index() due to lack of an EOF (End of File) check might have caused huge CPU consumption. When a crafted ASF file, claiming a large 'ict' field in the header but not containing sufficient backing data, was provided, the for loop would have consumed huge CPU and memory resources, since there was no EOF check inside the loop.

For Debian 8 'Jessie', these problems have been fixed in version 6:11.12-1~deb8u5.

We recommend that you upgrade your libav packages.

Please reference CVE/URL list for details

It was discovered that Libav incorrectly handled certain malformed media files. If a user were tricked into opening a crafted media file, an attacker could cause a denial of service via application crash, or possibly execute arbitrary code with the privileges of the user invoking the program.

Updated ffmpeg packages fix security vulnerabilities :

The tak_decode_frame function in libavcodec/takdec.c in FFmpeg before 2.0.4 does not properly validate a certain bits-per-sample value, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted TAK (aka Tom's lossless Audio Kompressor) data (CVE-2014-2097).

libavcodec/wmalosslessdec.c in FFmpeg before 2.0.4 uses an incorrect data-structure size for certain coefficients, which allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via crafted WMA data (CVE-2014-2098).

The msrle_decode_frame function in libavcodec/msrle.c in FFmpeg before 2.0.4 does not properly calculate line sizes, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted Microsoft RLE video data (CVE-2014-2099).

The mpegts_write_pmt function in the MPEG2 transport stream (aka DVB) muxer (libavformat/mpegtsenc.c) in FFmpeg before 2.0.4 allows remote attackers to have unspecified impact and vectors, which trigger an out-of-bounds write (CVE-2014-2263).

An integer overflow in LZO decompression in FFmpeg before 2.0.5 allows remote attackers to have an unspecified impact by embedding compressed data in a video file (CVE-2014-4610).

A heap-based buffer overflow in the encode_slice function in libavcodec/proresenc_kostya.c in FFmpeg before 2.0.6 can cause a crash, allowing a malicious image file to cause a denial of service (CVE-2014-5271).

libavcodec/iff.c in FFmpeg before 2.0.6 allows an attacker to have an unspecified impact via a crafted iff image, which triggers an out-of-bounds array access, related to the rgb8 and rgbn formats (CVE-2014-5272).

libavcodec/mjpegdec.c in FFmpeg before 2.0.6 considers only dimension differences, and not bits-per-pixel differences, when determining whether an image size has changed, which allows remote attackers to cause a denial of service (out-of-bounds access) or possibly have unspecified other impact via crafted MJPEG data (CVE-2014-8541).

libavcodec/utils.c in FFmpeg before 2.0.6 omits a certain codec ID during enforcement of alignment, which allows remote attackers to cause a denial of service (out-of-bounds access) or possibly have unspecified other impact via crafted JV data (CVE-2014-8542).

libavcodec/mmvideo.c in FFmpeg before 2.0.6 does not consider all lines of HHV Intra blocks during validation of image height, which allows remote attackers to cause a denial of service (out-of-bounds access) or possibly have unspecified other impact via crafted MM video data (CVE-2014-8543).

libavcodec/tiff.c in FFmpeg before 2.0.6 does not properly validate bits-per-pixel fields, which allows remote attackers to cause a denial of service (out-of-bounds access) or possibly have unspecified other impact via crafted TIFF data (CVE-2014-8544).

libavcodec/pngdec.c in FFmpeg before 2.0.6 accepts the monochrome-black format without verifying that the bits-per-pixel value is 1, which allows remote attackers to cause a denial of service (out-of-bounds access) or possibly have unspecified other impact via crafted PNG data (CVE-2014-8545).

Integer underflow in libavcodec/cinepak.c in FFmpeg before 2.0.6 allows remote attackers to cause a denial of service (out-of-bounds access) or possibly have unspecified other impact via crafted Cinepak video data (CVE-2014-8546).

libavcodec/gifdec.c in FFmpeg before 2.0.6 does not properly compute image heights, which allows remote attackers to cause a denial of service (out-of-bounds access) or possibly have unspecified other impact via crafted GIF data (CVE-2014-8547).

Off-by-one error in libavcodec/smc.c in FFmpeg before 2.0.6 allows remote attackers to cause a denial of service (out-of-bounds access) or possibly have unspecified other impact via crafted Quicktime Graphics (aka SMC) video data (CVE-2014-8548).

This updates provides ffmpeg version 2.0.6, which fixes these issues and several other bugs which were corrected upstream.
