CVE-2017-14056

Last modified

CVE-2017-14056 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 1.82% chance of exploitation in the next 30 days.
