Description Alexander Bergmann 2017-09-01 06:58:10 UTC 
CVE-2017-14056

In libavformat/rl2.c in FFmpeg 3.3.3, a DoS in rl2_read_header() due to
lack of an EOF (End of File) check might cause huge CPU and memory
consumption. When a crafted RL2 file, which claims a large
"frame_count" field in the header but does not contain sufficient
backing data, is provided, the loops (for offset and size tables) would
consume huge CPU and memory resources, since there is no EOF check
inside these loops.

Comment 1 Alexander Bergmann 2017-09-01 07:01:08 UTC 
As we have currently no official ffmpeg maintainer in openSUSE I've added the last 3 persons that are visible inside the changes file.

Feel free to submit a fix.
Comment 2 Jan Engelhardt 2017-09-01 11:18:07 UTC 
Uhm of course we have maintainer.

RL2 is not enabled in openSUSE.
