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)
