Description Alexander Bergmann 2017-09-01 07:11:03 UTC 
CVE-2017-14054

In libavformat/rmdec.c in FFmpeg 3.3.3, a DoS in ivr_read_header() due
to lack of an EOF (End of File) check might cause huge CPU consumption.
When a crafted IVR file, which claims a large "len" field in the header
but does not contain sufficient backing data, is provided, the first
type==4 loop would consume huge CPU resources, since there is no EOF
check inside the loop.

Comment 1 Alexander Bergmann 2017-09-01 07:11:38 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.
