VUL-0: CVE-2017-14056: ffmpeg: DoS in rl2_read_header() due to lack of an EOF (End of File) check
Last modified: 2021-09-11 02:36:12 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. Upstream fix: https://github.com/FFmpeg/FFmpeg/commit/96f24d1bee7fe7bac08e2b7c74db1a046c9dc0de References: http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2017-14056 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-14056
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.
Uhm of course we have maintainer. RL2 is not enabled in openSUSE.
