Detailsinfo

A vulnerability was found in ImageMagick (Image Processing Software) (the affected version unknown). It has been declared as critical. This vulnerability affects the function ExportIndexQuantum of the file MagickCore/quantum-export.c of the component PDF File Handler. The manipulation with an unknown input leads to a integer overflow vulnerability. The CWE definition for the vulnerability is CWE-190. The product performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

An integer overflow issue was discovered in ImageMagick's ExportIndexQuantum() function in MagickCore/quantum-export.c. Function calls to GetPixelIndex() could result in values outside the range of representable for the 'unsigned char'. When ImageMagick processes a crafted pdf file, this could lead to an undefined behaviour or a crash.

The weakness was disclosed 08/26/2022. The advisory is available at github.com. This vulnerability was named CVE-2021-20224 since 12/17/2020. Successful exploitation requires user interaction by the victim. Technical details are known, but there is no available exploit.
