DESCRIPTION:
Multiple vulnerabilities have been reported in FFmpeg, which can be
exploited by malicious people to cause a DoS (Denial of Service) and
potentially compromise a user's system.

1) Errors when processing MKV and Vorbis files can be exploited to
cause an out-of-bounds read.

For more information see vulnerability #3 in:
SA46815

2) An error when processing Vorbis files can be exploited to cause a
heap-based buffer overflow.

For more information see vulnerability #5 in:
SA46815

3) An error within the "process_audio_header_eacs()" function
(libavformat/electronicarts.c) can be exploited to cause a division
by zero via e.g. specially crafted TGV files.

4) An error within the "ff_pnm_decode_header()" function
(libavcodec/pnm.c) can be exploited to cause a division by zero via
e.g. specially crafted PAM files.

5) An error within the "decode_band_types()" function
(libavcodec/aacdec.c) can be exploited to cause an infinite loop via
e.g. specially crafted of PCM files.

6) An error within the "load_ipmovie_packet()" function
(libavformat/ipmovie.c) can be exploited to cause a division by zero
via e.g. specially crafted MVE files.

7) An error within the "decode_slice_thread()" function
(libavcodec/proresdec2.c) can be exploited to cause a crash due to an
out-of-bounds read via e.g. specially crafted MOV files.

8) Errors within the "mpeg1_decode_sequence()" and
"vcr2_init_sequence()" functions (libavcodec/mpeg12.c) can be
exploited to cause a crash via e.g. specially crafted MPEG2 TS
files.

9) A NULL-pointer dereference error within the "parse_bintree()"
function (libavcodec/indeo3.c) can be exploited to cause a crash via
e.g. specially crafted MOV files.

10) An error within the "get_ur_golomb_jpegls()" function
(libavcodec/golomb.h) can be exploited to cause an infinite loop via
e.g. specially crafted AVI files.

11) A NULL-pointer dereference error within the
"ff_ivi_output_plane()" function (libavcodec/ivi_common.c) can be
exploited to cause a crash via e.g. specially crafted media files
using the INDEO5 codec.

12) Errors within the handling of MVE files can be exploited to cause
a crash due to excessive memory consumption.

13) A NULL-pointer dereference error within the "tm2_read_stream()"
function (libavcodec/truemotion2.c) can be exploited to cause a crash
via e.g. specially crafted AVI files.

14) An error within the "avi_read_idx1()" function
(libavformat/avidec.c) can be exploited to cause an infinite loop via
e.g. specially crafted AVI files.

15) An error within the "adpcm_decode_frame()" function
(libavcodec/adpcm.c) can be exploited to cause a crash via e.g.
specially crafted WVE files.

16) An error within the "rl2_read_header()" function
(libavformat/rl2.c) can be exploited to cause a crash due to a
floating point exception.

17) A NULL-pointer dereference error within the
"avpriv_mpeg4audio_get_config()" function (libavcodec/mpeg4audio.c)
can be exploited to cause a crash.

18) An error within the "decodeTonalComponents()" function
(libavcodec/atrac3.c) can be exploited to cause a crash.

19) An error within the "avi_read_header()" function
(libavformat/avidec.c) can be exploited to cause a crash due to
memory consumption via specially crafted AVI files.

20) An error within the "txd_read_header()" function
(libavformat/txd.c) can be exploited to cause a crash due to memory
consumption via specially crafted TXD files.

21) Errors within the processing of THP files can be exploited to
cause a crash due to memory consumption.

22) An error within the "avi_read_packet()" function
(libavformat/avidec.c) can be exploited to cause an infinite loop via
specially crafted packages.

23) An integer overflow error within the "ff_j2k_dwt_init()" function
(libavcodec/j2k_dwt.c) can be exploited to cause a heap-based buffer
overflow.

24) An error within the "smacker_read_packet()" function
(libavformat/smacker.c) can be exploited to cause a crash due to
memory consumption via specially crafted SMK files.

25) An error within the "transcode_video()" function (ffmpeg.c) can
be exploited to cause a crash via e.g. specially crafted VC1 files.

26) A boundary error within the "smka_decode_frame()" function
(libavcodec/smacker.c) can be exploited to cause a crash due to
out-of-bounds reads via specially crafted SMK files.

27) An error within the "ff_mov_read_stsd_entries()" function
(libavformat/mov.c) can be exploited to cause an infinite loop via
specially crafted MOV files.

28) An error when decoding JPEG files in lowres mode can be exploited
to cause a crash via specially crafted JPEG files.

29) An error within the "sbr_qmf_synthesis()" function
(libavcodec/aacsbr.c) can be exploited to cause a memory corruption
via specially crafted media files.

30) An error within the "ff_h264_decode_seq_parameter_set()" function
(libavcodec/h264_ps.c) can be exploited to cause a crash via e.g.
specially crafted H264 files.

31) An error within the "mtv_read_header()" function
(libavformat/mtv.c) can be exploited to cause a floating point
exception via specially crafted MTV files.

32) Various other errors can be exploited to e.g. cause crashes due
to NULL-pointer dereferences, out-of-bounds reads, floating point
exceptions, integer overflows, excessive memory consumption and
invalid memory frees or cause infinite loops via specially crafted
media files.

SOLUTION:
Update to version 0.9.1.
