Currently, the security tracker lists the following issues for libav:

CVE-2010-3908

allows remote attackers to cause a denial of service (memory corruption
and application crash) or possibly execute arbitrary code via a
malformed WMV file.

Fixed in 0.5.4

CVE-2011-0722

Real Media decoder bug, fixed in 0.5.4

CVE-2011-0723

VC-1 decoder bug, fixed in 0.5.4

CVE-2011-1196

oggdec, heap corruption bug.

fixed in 0.7.1 but the patch does not apply 0.5, and I failed to reproduce. If
someone can, please get in touch with me.

CVE-2011-1198

ffmpeg-mt specific bug with mp4 files, Unreproducible with libav:
http://thread.gmane.org/gmane.comp.video.libav.devel/8507

CVE-2011-2160

extremly vague, no useful references given

CVE-2011-2161

APE decoder bug, fixed in 0.5.4

CVE-2011-2162

description on mitre is way too vague, the referenced madriva source
package does not contain any relevant patch to this issue.


All issues above are fixed in the 0.6 and 0.7 based packages in debian
unstable and experimental.

I have uploaded 0.5.4-1 to stable-security on March 6, with the
following changelog entry:

Can someone from the security team please check what's the problem with
the upload?
