CVE-2026-55510

Application crash via crafted 8BIM profile

Published Jul 1, 2026 · Updated Jul 1, 2026

Use-after-free in ImageMagick 6 before 6.9.13-51 and ImageMagick 7 before 7.1.2-26 allows local users to crash image identification. Get8BIMProperty mishandles the lifetime of an 8BIM resource-name pointer before ConvertMacRomanToUTF8 consumes it; the patch preserves the pointer state and skips conversion when no resource exists. A user or application must identify attacker-supplied image content with the triggering format string, and the documented consequence is a process crash.
