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

  • FFmpeg 4.2 is affected by a Divide By Zero issue via libavcodec/lpc.h, which allows a remote malicious user to cause a Denial of Service. (CVE-2020-20445)

  • FFmpeg 4.2 is affected by a Divide By Zero issue via libavcodec/aacpsy.c, which allows a remote malicious user to cause a Denial of Service. (CVE-2020-20446)

  • Denial of Service issue in FFmpeg 4.2 due to resource management errors via fftools/cmdutils.c.
    (CVE-2020-20451)

  • 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)

  • A Denial of Service vulnerability exists in FFmpeg 4.2 due to a memory leak in avcodec_alloc_context3 at options.c. (CVE-2020-22037)

  • A Denial of Service vulnerability exists in FFmpeg 4.2 due to a memory leak in the av_buffersrc_add_frame_flags function in buffersrc. (CVE-2020-22041)

  • A Denial of Service vulnerability exists in FFmpeg 4.2 due to a memory leak in the url_open_dyn_buf_internal function in libavformat/aviobuf.c. (CVE-2020-22044)

  • 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)

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