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


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


Real Media decoder bug, fixed in 0.5.4


VC-1 decoder bug, fixed in 0.5.4


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.


ffmpeg-mt specific bug with mp4 files, Unreproducible with libav:


extremly vague, no useful references given


APE decoder bug, fixed in 0.5.4


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:
