Detailsinfo

A vulnerability, which was classified as critical, has been found in ImageMagick up to 6.9.13-56/7.1.2-31. Affected by this issue is some unknown functionality of the component Security Policy. The manipulation with an unknown input leads to a heap-based overflow vulnerability. Using CWE to declare the problem leads to CWE-122. A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc(). Impacted is integrity, and availability. CVE summarizes:

ImageMagick before 6.9.13-57 and 7.x before 7.1.2-32 lacks proper synchronization when the security policy is accessed, so simultaneous reads and writes of the policy by multiple threads trigger a race condition that causes a heap buffer over-write. An attacker able to induce concurrent security policy access can crash the application, causing a denial of service.

The advisory is available at github.com. This vulnerability is handled as CVE-2026-109279 since 10/12/2026. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. The technical details are unknown and an exploit is not available.

Upgrading to version 6.9.13-57 or 7.1.2-32 eliminates this vulnerability.
