CVE-2025-43965

Service interruption via stale MIFF image depth

Published Apr 23, 2025 · Updated Apr 26, 2025

Use-after-free in ImageMagick before 7.1.1-44 allows local users to interrupt MIFF image processing with a crafted image. ReadMIFFImage calls SetQuantumFormat but fails to copy the resulting quantum depth into image->depth, leaving later processing with inconsistent depth state. Processing an attacker-supplied MIFF file is required, and the documented consequence is process memory misuse and service interruption.
