Doc Text:
A flaw was found in ImageMagick. When the PNM coder processes a specially crafted or sufficiently large image, it can reach a memory resource limit. The application fails to handle the memory allocation, leading to a null pointer dereference. This can result in a denial of service, causing the application to crash.

Description OSIDB Bzimport 2026-09-22 17:09:11 UTC 
ImageMagick before 7.1.2-31 and before 6.9.13-56 contains a NULL pointer dereference in the PNM coder. When the coder reaches a memory (resource) limit at a specific point during processing, the failed allocation is not handled and a NULL pointer is dereferenced, which can lead to a denial of service (application crash) when processing a specially crafted or sufficiently large PNM image.
