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.

The vulnerabilities are caused due to various errors within the 4xm,
ADPCM IMA Electronic Arts EACS, ANM, Electronic Arts CMV, PTX, QDM2,
QuickDraw, TIFF, Tiertex Limited SEQ, aac, bink, flic, h264, indeo2,
jpeg 2000, mpc v8, rasterfile, shorten, sun raster, vmd audio, vmd
video, wmapro, wmavoice, and xan decoders, the 4X Technologies,
Deluxe Paint Animation, avi, and avs demuxers, the libx264 interface
to the x264 encoder, the unsharp filter, and the mov muxer, which can
be exploited to e.g. cause NULL pointer dereferences, out-of-bounds
reads and writes, double-frees, and buffer overflows via e.g.
specially crafted media content.

The vulnerabilities are reported in versions prior to 0.7.6 and
0.8.5.

1) A boundary error within the "cinvideo_decode_frame()" function
(libavcodec/dsicinav.c) can be exploited to cause a heap based buffer
overflow via a Delphine Software International CIN (*.CIN) file
containing a frame with an overly large number of palette colors.

2) The "qdm2_decode_init()" function (libavcodec/qdm2.c) does not
properly limit the number of channels, which can be exploited to e.g.
cause an out-of-bounds write within the "fill_tone_level_array()"
function (libavcodec/qdm2.c) via specially crafted media files.

SOLUTION:
Update to version 0.7.6 and 0.8.5.

PROVIDED AND/OR DISCOVERED BY:
Reported by the vendor.
