CVE-2025-65955

Heap corruption via incorrect font pointer free

Published Dec 2, 2025 · Updated Jun 23, 2026

Memory corruption in ImageMagick before 6.9.13-34 and 7.0.1-0 through 7.1.2-8 allows local users to crash a process. Options::fontFamily frees _drawInfo->font instead of _drawInfo->family when passed an empty string, leaving a dangling font pointer that later cleanup re-frees or dereferences. Triggering requires an application that calls the Magick++ method; ImageMagick command-line tools do not expose this code path.
