Multiple vulnerabilities have been found in libav:

  • CVE-2015-1872

    The ff_mjpeg_decode_sof function in libavcodec/mjpegdec.c in Libav before 0.8.18 does not validate the number of components in a JPEG-LS Start Of Frame segment, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted Motion JPEG data.

  • CVE-2015-5479

    The ff_h263_decode_mba function in libavcodec/ituh263dec.c in Libav before 11.5 allows remote attackers to cause a denial of service (divide-by-zero error and application crash) via a file with crafted dimensions.

  • CVE-2016-7393

    The aac_sync function in libavcodec/aac_parser.c in Libav before 11.5 is vulnerable to a stack-based buffer overflow.

For Debian 7 Wheezy, these problems have been fixed in version 6:0.8.18-0+deb7u1.

We recommend that you upgrade your libav packages.
