Description Matti Bickel (RETIRED) gentoo-dev

2009-02-01 14:30:42 UTC

From the advisory:
FFmpeg contains a type conversion vulnerability while parsing malformed 4X 
movie files. The vulnerability may be exploited by a (remote) attacker to 
execute arbitrary code in the context of FFmpeg or an application using 
the FFmpeg library.

Upstream has fixed this in svn r16846, i haven't found a release yet.

media-video, do you pull updates from trunk and can provide an ebuild? Or do we wait for the ffmpeg folks for a release?

rev 16916, aka 0.4.9_p20090201 is in the tree; don't forget all the packages bundling ffmpeg too

thanks for the quick response.

target keywords for: media-video/ffmpeg-0.4.9_p20090201
alpha, amd64, arm, hppa, ia64, ppc, ppc64, sparc, x86, ~x86-fbsd

Please do, we have 10 days maximum for a glsa, so a little testing on this complex piece would not hurt.
