Mandriva Linux Security Advisory MDVSA-2014:129

Package : ffmpeg
Date : July 9, 2014
Affected: Business Server 1.0

Problem Description:

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.
