• Product: Gentoo Security

[Description Alexis Ballier 2012-01-06 13:15:51 UTC]

from ffmpeg.org:
We have made a new point release, (0.9.1). It contains many bug and security fixes, amongth them CVE-2011-3893 and CVE-2011-3895.

(those are chrome CVE's but it seems the culprit was ffmpeg, didnt check if those were not fixed in 0.7.8 for example)

iow: nothing moved, so my vote would be to cc arches and let them do the tinderbox run. i've asked diego for a tinderbox run prior to unmasking ffmpeg 0.8, didnt get it, you can see in that bug that there were no reply either for 0.9. even arch teams didnt move for rekeywording >=0.8, which bug was opened 1.5 months ago. if noone takes action, this can remain as such for a couple more months i think.
