Atrac Sample Decoding Vulnerability
Hello,
Recently I have checked some of mine files and one of them crash VLC. It is interesting since it's the one from the recent RealPlayer security update [1] which was exploitable. I attached repro and seed file for you.
[1] CVE-2012-0928 @ http://service.real.com/realplayer/security/02062012_player/en/
Cheers, Andrzej
PS. I hope I didn't screwed up anything, first time using TRAC.

I couldn't attach files due to file size so here's the link - http://dl.dropbox.com/u/30447464/Crash.zip
Stacktrace suggests it could potentially be a libavcodec bug?
