Detailsinfo

A vulnerability was found in ImageMagick up to 6.9.13-39/7.1.2-14. It has been declared as problematic. Affected by this vulnerability is the function DecodeImage of the component PCD File Handler. The manipulation with an unknown input leads to a resource consumption vulnerability. The CWE definition for the vulnerability is CWE-400. The product does not properly control the allocation and maintenance of a limited resource, thereby enabling an actor to influence the amount of resources consumed, eventually leading to the exhaustion of available resources. As an impact it is known to affect availability. The summary by CVE is:

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-15 and 6.9.13-40, when a PCD file does not contain a valid Sync marker, the DecodeImage() function becomes trapped in an infinite loop while searching for the Sync marker, causing the program to become unresponsive and continuously consume CPU resources, ultimately leading to system resource exhaustion and denial of service. Versions 7.1.2-15 and 6.9.13-40 contain a patch.

The advisory is shared at github.com. This vulnerability is known as CVE-2026-24485 since 01/23/2026. The exploitation appears to be easy. The attack can be launched remotely. The exploitation doesn't need any form of authentication. It demands that the victim is doing some kind of user interaction. Technical details are known, but no exploit is available.
