Integer overflow in the get_len function in libavutil/lzo.c in Libav before 0.8.13, 9.x before 9.14, and 10.x before 10.2 allows remote attackers to execute arbitrary code via a crafted Literal Run.

Please reference CVE/URL list for details

The remote host is affected by the vulnerability described in GLSA-201502-08 (Libav: Multiple vulnerabilities)

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

    A remote attacker could entice a user to open a specially crafted media       file in an application linked against Libav, possibly resulting in       execution of arbitrary code with the privileges of the application or a       Denial of Service condition.
  Workaround :

    There is no known workaround at this time.

Don A. Baley discovered an integer overflow in the lzo compression handler which could result in the execution of arbitrary code.

Multiple vulnerabilities has been discovered and corrected in ffmpeg :

Multiple unspecified vulnerabilities in libavcodec/wmalosslessdec.c in FFmpeg before 0.11 have unknown impact and attack vectors related to (1) size of mclms arrays, (2) a get_bits(0) in decode_ac_filter, and (3) too many bits in decode_channel_residues(). (CVE-2012-2795).

libavcodec/wmalosslessdec.c in FFmpeg before 2.1.4 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 2.1.4 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, possibly 2.1 and earlier, allows remote attackers to have unspecified impact and vectors, which trigger an out-of-bounds write (CVE-2014-2263).

A use-after-free vulnerability in FFmpeg before 1.1.9 involving seek operations on video data could allow remote attackers to cause a denial of service (CVE-2012-5150).

An integer overflow can occur when processing any variant of a literal run in the av_lzo1x_decode function (CVE-2014-4609, CVE-2014-4610).

The updated packages have been upgraded to the 0.10.14 version which is not vulnerable to these issues.
