"The remote SUSE Linux SLED15 / SLES15 host has packages installed that are affected by multiple vulnerabilities as
referenced in the SUSE-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)

  - 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. (CVE-2020-20448)

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

  - 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)

  - A heap-based Buffer Overflow vulnerability in FFmpeg 4.2 at libavcodec/get_bits.h when writing .mov files,
    which might lead to memory corruption and other potential consequences. (CVE-2020-22016)

  - A heap-based Buffer Overflow vulnerability exists in FFmpeg 4.2 at ff_fill_rectangle in
    libavfilter/drawutils.c, which might lead to memory corruption and other potential consequences.
    (CVE-2020-22017)

  - Buffer Overflow vulnerability in FFmpeg 4.2 at convolution_y_10bit in libavfilter/vf_vmafmotion.c, which
    could let a remote malicious user cause a Denial of Service. (CVE-2020-22019)

  - Buffer Overflow vulnerability in FFmpeg 4.2 in the build_diff_map function in libavfilter/vf_fieldmatch.c,
    which could let a remote malicious user cause a Denial of Service. (CVE-2020-22020)

  - Buffer Overflow vulnerability in FFmpeg 4.2 at filter_edges function in libavfilter/vf_yadif.c, which
    could let a remote malicious user cause a Denial of Service. (CVE-2020-22021)

  - A heap-based Buffer Overflow vulnerability exists in FFmpeg 4.2 in filter_frame at
    libavfilter/vf_fieldorder.c, which might lead to memory corruption and other potential consequences.
    (CVE-2020-22022)

  - A heap-based Buffer Overflow vulnerabililty exists in FFmpeg 4.2 in filter_frame at
    libavfilter/vf_bitplanenoise.c, which might lead to memory corruption and other potential consequences.
    (CVE-2020-22023)

  - A heap-based Buffer Overflow vulnerability exists in gaussian_blur at libavfilter/vf_edgedetect.c, which
    might lead to memory corruption and other potential consequences. (CVE-2020-22025)

  - 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.
    (CVE-2020-22031)

  - A heap-based Buffer Overflow vulnerability exists FFmpeg 4.2 at libavfilter/vf_edgedetect.c in
    gaussian_blur, which might lead to memory corruption and other potential consequences. (CVE-2020-22032)

  - A heap-based Buffer Overflow Vulnerability exists FFmpeg 4.2 at libavfilter/vf_vmafmotion.c in
    convolution_y_8bit, which could let a remote malicious user cause a Denial of Service. (CVE-2020-22033)

  - A heap-based Buffer Overflow vulnerability exists FFmpeg 4.2 at libavfilter/vf_floodfill.c, which might
    lead to memory corruption and other potential consequences. (CVE-2020-22034)

  - A Denial of Service vulnerability exists in FFmpeg 4.2 due to a memory leak in the
    ff_v4l2_m2m_create_context function in v4l2_m2m.c. (CVE-2020-22038)

  - A Denial of Service vulnerability exists in FFmpeg 4.2 due to a memory leak in the inavi_add_ientry
    function. (CVE-2020-22039)

  - A Denial of Service vulnerability exists in FFmpeg 4.2 due to a memory leak at the fifo_alloc_common
    function in libavutil/fifo.c. (CVE-2020-22043)

  - 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)
