CVE-2026-23952: Dlemstra Magick.net

High severity, CVSS 7.5. EPSS: 0.5% chance of exploitation in the next 30 days.

ImageMagick is free and open-source software used for editing and manipulating digital images. Versions 14.10.1 and below have a NULL pointer dereference vulnerability in the MSL (Magick Scripting Language) parser when processing <comment> tags before images are loaded. This can lead to DoS attack due to assertion failure (debug builds) or NULL pointer dereference (release builds). This issue is fixed in version 14.10.2.

Affected products

• Dlemstra Magick.net: before 14.10.2 (fixed in 14.10.2)
• ImageMagick ImageMagick: before 6.9.13-38 (fixed in 6.9.13-38); from 7.0.0-0, before 7.1.2-13 (fixed in 7.1.2-13)
