Subject: CVE Requests for FFmpeg 0.9.1
Hi
Id like to request some CVE #s for ffmpeg 0.9.1.
to lookup the git hashes see:
http://source.ffmpeg.org/?p=ffmpeg.git;a=summary
or put "http://source.ffmpeg.org/?p=ffmpeg.git;a=commitdiff;h="
before each hash
I tried to sort the issues a little according to type to make this huge list a
bit less ugly. Also feel free to skip things considered too minor, iam
not sure where the threshold of "too minor" is.
