Publication date: 2026-06-10

Last updated on: 2026-06-11

Assigner: GitHub, Inc.

Description

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 6.9.13-48 and 7.1.2-24, a missing check of a return value could lead to a heap buffer over-write in the MAT decoder on 32-bit systems. This issue has been patched in versions 6.9.13-48 and 7.1.2-24.
