FFmpeg 4.2 is affected by a Divide By Zero issue via libavcodec/aaccoder,
which allows a remote malicious user to cause a Denial of Service.
(CVE-2020-20453)

Buffer Overflow vulnerability exists in FFmpeg 4.1 via apng_do_inverse_blend
in libavcodec/pngenc.c, which could let a remote malicious user cause a
Denial of Service. (CVE-2020-21041)

Buffer Overflow vulnerability in FFmpeg 4.2 in mov_write_video_tag due to
the out of bounds in libavformat/movenc.c, which could let a remote
malicious user obtain sensitive information, cause a Denial of Service, or
execute arbitrary code. (CVE-2020-22015)
