The remote SUSE Linux SUSE15 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2021:2919-1 advisory.

  - A denial of service in the subtitle decoder in FFmpeg 3.2 and 4.1 allows attackers to hog the CPU via a     crafted video file in Matroska format, because handle_open_brace in libavcodec/htmlsubtitles.c has a     complex format argument to sscanf. (CVE-2019-9721)

  - A heap-use-after-free in the av_freep function in libavutil/mem.c of FFmpeg 4.2 allows attackers to     execute arbitrary code. (CVE-2020-21688)

  - A heap-use-after-free in the mpeg_mux_write_packet function in libavformat/mpegenc.c of FFmpeg 4.2 allows     to cause a denial of service (DOS) via a crafted avi file. (CVE-2020-21697)

  - A Denial of Service vulnerability exists in FFmpeg 4.2 due to a memory leak in the avpriv_float_dsp_allocl     function in libavutil/float_dsp.c. (CVE-2020-22046)

  - A Denial of Service vulnerability exists in FFmpeg 4.2 due to a memory leak in the ff_frame_pool_get     function in framepool.c. (CVE-2020-22048)

  - A Denial of Service vulnerability exists in FFmpeg 4.2 due to a memory leak in the wtvfile_open_sector     function in wtvdec.c. (CVE-2020-22049)

  - A Denial of Service vulnerability exists in FFmpeg 4.2 due to a memory leak in the av_dict_set function in     dict.c. (CVE-2020-22054)

  - libavcodec/dnxhddec.c in FFmpeg 4.4 does not check the return value of the init_vlc function, a similar     issue to CVE-2013-0868. (CVE-2021-38114)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-2818 advisory.

    (CVE-2020-20451)

  - A Denial of Service vulnerability exists in FFmpeg 4.2 due to a memory leak in the avpriv_float_dsp_allocl     function in libavutil/float_dsp.c. (CVE-2020-22046)

  - A Denial of Service vulnerability exists in FFmpeg 4.2 due to a memory leak in the ff_frame_pool_get     function in framepool.c. (CVE-2020-22048)

  - A Denial of Service vulnerability exists in FFmpeg 4.2 due to a memory leak in the wtvfile_open_sector     function in wtvdec.c. (CVE-2020-22049)

  - A Denial of Service vulnerability exists in FFmpeg 4.2 due to a memory leak in the av_dict_set function in     dict.c. (CVE-2020-22054)

  - adts_decode_extradata in libavformat/adtsenc.c in FFmpeg 4.4 does not check the init_get_bits return     value, which is a necessary step because the second argument to init_get_bits can be crafted.
    (CVE-2021-38171)

  - FFmpeg version (git commit de8e6e67e7523e48bb27ac224a0b446df05e1640) suffers from a an assertion failure     at src/libavutil/mathematics.c. (CVE-2021-38291)
