DESCRIPTION:
Two 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 Sunplus JPEG decoder can be exploited by e.g.
tricking a user into opening a specially crafted AMV file.

2) A race condition error exists within the
"av_log_default_callback()" function in libavutil/log.c.

SOLUTION:
Update to version 0.6.3.

PROVIDED AND/OR DISCOVERED BY:
1) Dominic Chell, NGS Secure
2) Reported by the vendor.
