Bug#496612: ffmpeg: dca decoder crashes on a crafted file

Package: ffmpeg
Version: 0.svn20080206-8
Severity: normal

Try to ffplay or convert the attached crash.dts file (not a valid DTS stream, 
produced by accident when I made a wrong change to my not-yet-released DTS 
encoder) - ffmpeg segfaults at least on amd64, which may have security 
implications. This crash is not present in the latest SVN version of ffmpeg 
(although I don't know which revision fixes this), and it also has some 
correctness fixes that you may want to backport (dcadata.h: revision 14964, 
dca.c: revisions 14937 and 14917).
