    2024-06-06: CVE-2021-20309 was added to this advisory.

    A flaw was found in ImageMagick, where a division by zero in WaveImage() of MagickCore/visual-effects.c
    may trigger undefined behavior via a crafted image file submitted to an application using ImageMagick. The
    highest threat from this vulnerability is to system availability. (CVE-2021-20309)

    A vulnerability was found in ImageMagick where heap use-after-free was found in coders/bmp.c.
    (CVE-2023-5341)

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

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