FFmpeg 4.1.3 is affected by a Divide By Zero issue via libavcodec/ratecontrol.c, which allows a remote malicious user to cause a Denial of Service.

The remote SUSE Linux SUSE15 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2021:2322-1 advisory.

  - In FFmpeg before 4.2, avcodec_open2 in libavcodec/utils.c allows a NULL pointer dereference and possibly     unspecified other impact when there is no valid close function pointer. (CVE-2019-17539)

  - FFmpeg 2.8 and 4.2.3 has a use-after-free via a crafted EXTINF duration in an m3u8 file because     parse_playlist in libavformat/hls.c frees a pointer, and later that pointer is accessed in     av_probe_input_format3 in libavformat/format.c. (CVE-2020-13904)

  - Buffer Overflow vulnerability exists in FFmpeg 4.2 in the config_input function at     libavfilter/af_tremolo.c, which could let a remote malicious user cause a Denial of Service.
    (CVE-2020-22026)

  - A Heap-based Buffer Overflow vulnerability exists in FFmpeg 4.2 at libavfilter/vf_w3fdif.c in     filter16_complex_low, which might lead to memory corruption and other potential consequences.
