CVE-2026-109279ImageMagick before 6.9.13-57 and 7.x before 7.1.2-32 Heap Buffer Overflow via Concurrent Security Policy Access
Low 2.5
In plain English
A low-severity race condition in ImageMagick from ImageMagick. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.1% (higher than 0% of all known vulnerabilities). Fixed versions are available - upgrade the affected package.
Official description
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.
