multiple vulnerabilities as referenced in the USN-6180-1 advisory.

  - An off-by-one error in the DecodeBlock function in codec/sdl_image.c in VideoLAN VLC media player before
    3.0.9 allows remote attackers to cause a denial of service (memory corruption) via a crafted image file.
    NOTE: this may be related to the SDL_Image product. (CVE-2019-19721)

  - A heap-based buffer overflow in the hxxx_AnnexB_to_xVC function in modules/packetizer/hxxx_nal.c in
    VideoLAN VLC media player before 3.0.11 for macOS/iOS allows remote attackers to cause a denial of service
    (application crash) or execute arbitrary code via a crafted H.264 Annex-B video (.avi for example) file.
    (CVE-2020-13428)

  - A buffer overflow vulnerability in the __Parse_indx component of VideoLAN VLC Media Player 3.0.11 allows
    attackers to cause an out-of-bounds read via a crafted .avi file. (CVE-2021-25801)

  - A buffer overflow vulnerability in the AVI_ExtractSubtitle component of VideoLAN VLC Media Player 3.0.11
    allows attackers to cause an out-of-bounds read via a crafted .avi file. (CVE-2021-25802)

  - A buffer overflow vulnerability in the vlc_input_attachment_New component of VideoLAN VLC Media Player
    3.0.11 allows attackers to cause an out-of-bounds read via a crafted .avi file. (CVE-2021-25803)

  - A NULL-pointer dereference in Open in avi.c of VideoLAN VLC Media Player 3.0.11 can a denial of service
    (DOS) in the application. (CVE-2021-25804)

  - An integer overflow in the VNC module in VideoLAN VLC Media Player through 3.0.17.4 allows attackers, by
    tricking a user into opening a crafted playlist or connecting to a rogue VNC server, to crash VLC or
    execute code under some conditions. (CVE-2022-41325)

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