CVE-2019-13304

ImageMagick versión 7.0.8-50 Q16 tiene un desbordamiento de búfer basado en pila en coders/pnm.c en WritePNMImage debido a una asignación modificada.

A stack-based buffer overflow was discovered in ImageMagick in the way it writes PNM images due to a misplaced assignment. Applications compiled against ImageMagick libraries that accept untrustworthy images or write PNM images may be vulnerable to this flaw. An attacker could abuse this flaw by providing a specially crafted image to make the application crash or potentially execute code.

It was discovered that ImageMagick incorrectly handled certain malformed image files. If a user or automated system using ImageMagick were tricked into opening a specially crafted image, an attacker could exploit this to cause a denial of service or possibly execute code with the privileges of the user invoking the program.
