CVE-2011-4352

Published: 25 November 2011

Integer overflow in the vp3_dequant function in the VP3 decoder (vp3.c) in libavcodec in FFmpeg 0.5.x before 0.5.7, 0.6.x before 0.6.4, 0.7.x before 0.7.9, and 0.8.x before 0.8.8; and in Libav 0.5.x before 0.5.6, 0.6.x before 0.6.4, and 0.7.x before 0.7.3 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted VP3 stream, which triggers a buffer overflow.

Priority

Medium

Notes

AuthorNote
mdeslaur
ffmpeg-extra in multiverse needs to have matching version
libav-extra is built with tarball produced by libav package
libav doesn't seem to have equivalent patch yet as of 2012-12-22
See thread: http://thread.gmane.org/gmane.comp.video.libav.devel/15121
this fixes NGS00145
