DESCRIPTION:
Some vulnerabilities have been reported in FFmpeg, which can be
exploited by malicious people to cause a DoS (Denial of Service) and
potentially compromise an application using the library.

1) An error within the QDM2 decoder (libavcodec/qdm2.c) can be
exploited to cause a buffer overflow.

2) An integer overflow error within the "vp3_dequant()" function
(libavcodec/vp3.c) can be exploited to cause a buffer overflow.

3) Errors within the "av_image_fill_pointers()", the
"vp5_parse_coeff()", and the "vp6_parse_coeff()" functions can be
exploited to trigger out-of-bounds reads.

The vulnerabilities are reported in versions prior to 0.7.8 and
0.8.7.

SOLUTION:
Update to version 0.7.8 or 0.8.7.

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