- CVE-2021-20312: A flaw was found in ImageMagick in versions 7.0.11, where an integer overflow in WriteTHUMBNAILImage of coders/thumbnail.c may trigger undefined behavior via a crafted image file that is submitted by an attacker and processed by an application using ImageMagick.

- CVE-2021-20311: A flaw was found in ImageMagick in versions before 7.0.11, where a division by zero in sRGBTransformImage() in the MagickCore/colorspace.c may trigger undefined behavior via a crafted image file that is submitted by an attacker processed by an application using ImageMagick.

- CVE-2021-20310: A flaw was found in ImageMagick in versions before 7.0.11, where a division by zero ConvertXYZToJzazbz() of MagickCore/colorspace.c may trigger undefined behavior via a crafted image file that is submitted by an attacker and processed by an application using ImageMagick.

- CVE-2021-20309: A flaw was found in ImageMagick in versions before 7.0.11, 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.

- And several others...

The remote Windows host has a version of ImageMagick installed that is prior to 6.9.11-62 or 7.0.x prior to 7.0.10-62.
It is, therefore, affected by following vulnerablities.

  - A flaw was found in ImageMagick in coders/webp.c. An attacker who submits a crafted file that is processed     by ImageMagick could trigger undefined behavior in the form of math division by zero. The highest threat from     this vulnerability is to system availability. (CVE-2021-20245)

  - A flaw was found in ImageMagick in MagickCore/resample.c. An attacker who submits a crafted file that is     processed by ImageMagick could trigger undefined behavior in the form of math division by zero. The highest     threat from this vulnerability is to system availability. (CVE-2021-20246)
