CVE reports :

Several vulnerabilities have been discovered in ImageMagick :

  • CVE-2021-20309: A flaw was found in ImageMagick in versions before 6.9.12, 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.

  • CVE-2021-20176: A divide-by-zero flaw was found in ImageMagick 6.9.11-57 in gem.c. This flaw allows an attacker who submits a crafted file that is processed by ImageMagick to trigger undefined behavior through a division by zero.

  • CVE-2020-29599: ImageMagick before 6.9.11-40 mishandles the
    -authenticate option, which allows setting a password for password-protected PDF files.

  • And maybe some others…
