Dear Maintainer,

I have here another series of CVEs for libav. Some of these are fixed, some
of these I was not able to check. Those without comment were checked by me
and seem valid - at least to me.

CVE-2013-0845
CVE-2013-0846
CVE-2013-0847 - vim '+/while (avio_tell(s->pb) < end' libavformat/id3v2.c
  above command brings you to the suspected problem position in libav, the
  problem looks solved to me
  This one is actually for libavformat, but I include it here for simplicity
CVE-2013-0848 - I was not able to find the problem in libav
CVE-2013-0849 - fixed in experimental
CVE-2013-0850 - seems fixed in experimental
CVE-2013-0851
CVE-2013-0852
CVE-2013-0853
CVE-2013-0854 - fixed in experimental
CVE-2013-0855 - looks invalid as the problem is checked in alac_set_info
CVE-2013-0856
CVE-2013-0857
CVE-2013-0858 - I was not able to find the problem in libav
CVE-2013-0860 - I was not able to find the problem in libav
CVE-2013-0861
CVE-2013-0865 - fixed in experimental
CVE-2013-0866 - looks fixed. am I correct?
CVE-2013-0867 - I was not able to find the problem in libav
CVE-2013-0868
CVE-2013-0869 - looks fixed. am I correct?
CVE-2013-0870 - seems to be invalid - relevant code fragment is not present
  in libav
CVE-2013-0873 - looks fixed. am I correct?
CVE-2013-0874 - seems to be invalid - relevant code fragment is not present
  in libav
CVE-2013-3670 looks valid - libav commits given in security tracker fix
  different things AFAICS
CVE-2013-3672
CVE-2013-3674

I hope these cses are a bit more well-defined as those I sent in January.

cu soon, hopefully,
