Several security issues have been corrected in multiple demuxers and
decoders of the libav multimedia library. A full list of the changes is
available at
http://git.libav.org/?p=libav.git;a=blob;f=Changelog;hb=refs/tags/v0.8.15
For the stable distribution (wheezy), these problems have been fixed in
version 6:0.8.15-1.
For the unstable distribution (sid), these problems will be fixed soon.
We recommend that you upgrade your libav packages.
