Integer Overflow vulnerability in function filter_prewitt in libavfilter/vf_convolution.c in Ffmpeg 4.2.1, allows attackers to cause a Denial of Service or other unspecified impacts.

The remote Ubuntu 18.04 ESM / 20.04 ESM / 22.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6449-1 advisory.

    It was discovered that FFmpeg incorrectly managed memory resulting

    in a memory leak. An attacker could possibly use this issue to cause a denial of service via application     crash. This issue only

    affected Ubuntu 18.04 LTS and Ubuntu 20.04 LTS. (CVE-2020-22038)

    It was discovered that FFmpeg incorrectly handled certain input files,

    leading to an integer overflow. An attacker could possibly use this issue to cause a denial of service via     application crash. This issue only

    affected Ubuntu 20.04 LTS. (CVE-2020-20898, CVE-2021-38090,

    CVE-2021-38091, CVE-2021-38092, CVE-2021-38093, CVE-2021-38094)

    It was discovered that FFmpeg incorrectly managed memory, resulting in a memory leak.

    If a user or automated system were tricked into

    processing a specially crafted input file, a remote attacker could possibly use this issue to cause a     denial of service, or execute

    arbitrary code. (CVE-2022-48434)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:0005-1 advisory.

  - Buffer Overflow vulnerability in function config_input in libavfilter/vf_gblur.c in Ffmpeg 4.2.1, allows     attackers to cause a Denial of Service or other unspecified impacts. (CVE-2020-20891)

  - An issue was discovered in function filter_frame in libavfilter/vf_lenscorrection.c in Ffmpeg 4.2.1,     allows attackers to cause a Denial of Service or other unspecified impacts due to a division by zero.
    (CVE-2020-20892)

  - An issue was discovered in function latm_write_packet in libavformat/latmenc.c in Ffmpeg 4.2.1, allows     attackers to cause a Denial of Service or other unspecified impacts due to a Null pointer dereference.
    (CVE-2020-20896)

  - A CWE-125: Out-of-bounds read vulnerability exists in long_term_filter function in g729postfilter.c in     FFmpeg 4.2.1 during computation of the denominator of pseudo-normalized correlation R'(0), that could     result in disclosure of information. (CVE-2020-20902)

  - 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 is affected by: memory leak in     the link_filter_inouts function in libavfilter/graphparser.c. (CVE-2020-22042)

  - decode_frame in libavcodec/exr.c in FFmpeg 4.3.1 has an out-of-bounds write because of errors in     calculations of when to perform memset zero operations. (CVE-2020-35965)

  - Prior to ffmpeg version 4.3, the tty demuxer did not have a 'read_probe' function assigned to it. By     crafting a legitimate ffconcat file that references an image, followed by a file the triggers the tty     demuxer, the contents of the second file will be copied into the output file verbatim (as long as the     `-vcodec copy` option is passed to ffmpeg). (CVE-2021-3566)

  - Integer Overflow vulnerability in function filter_prewitt in libavfilter/vf_convolution.c in Ffmpeg 4.2.1,     allows attackers to cause a Denial of Service or other unspecified impacts. (CVE-2021-38092)

  - Integer Overflow vulnerability in function filter_robert in libavfilter/vf_convolution.c in Ffmpeg 4.2.1,     allows attackers to cause a Denial of Service or other unspecified impacts. (CVE-2021-38093)

  - Integer Overflow vulnerability in function filter_sobel in libavfilter/vf_convolution.c in Ffmpeg 4.2.1,     allows attackers to cause a Denial of Service or other unspecified impacts. (CVE-2021-38094)

  - An issue was discovered in the FFmpeg package, where vp3_decode_frame in libavcodec/vp3.c lacks check of     the return value of av_malloc() and will cause a null pointer dereference, impacting availability.
