Please assign CVEs. Maybe someone wants to have a look if other issues in those releases are security relevant: http://git.videolan.org/?p=ffmpeg.git&a=shortlog&h=n0.7.8 -- Hanno Böck mail/jabber: hanno@...eck.de GPG: BBB51E42 http://www.hboeck.de/ Download attachment "signature.asc" of type "application/pgp-signature" (837 bytes)
