CVE-2025-55160: ImageMagick

Medium severity, CVSS 5.3. EPSS: 0.4% chance of exploitation in the next 30 days.

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 6.9.13-27 and 7.1.2-1, there is undefined behavior (function-type-mismatch) in splay tree cloning callback. This results in a deterministic abort under UBSan (DoS in sanitizer builds), with no crash in a non-sanitized build. This issue has been patched in versions 6.9.13-27 and 7.1.2-1.

Affected products

• ImageMagick ImageMagick: before 6.9.13-27 (fixed in 6.9.13-27); from 7.0.0-0, before 7.1.2-1 (fixed in 7.1.2-1)
