CVE-2017-14056 - log back

CVE-2017-14056 created at 25 Sep 2019 19:31:40
Severity	+ Low
Remote	+ Local
Type	+ Denial of service
Description	+ 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.
