Mandriva Linux Security Advisory MDVSA-2015:173
http://www.mandriva.com/en/support/security/
_______________________________________________________________________

Package : ffmpeg
Date : March 30, 2015
Affected: Business Server 2.0
_______________________________________________________________________

Problem Description:

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.
