Doc Text:
A flaw was found in ImageMagick, a software used for editing and manipulating digital images. This vulnerability, a memory leak, occurs when the software processes certain image files. Specifically, during image writing operations, if an error occurs, allocated memory is not properly released. A remote attacker could exploit this by providing a specially crafted image, leading to resource exhaustion and a denial of service (DoS), making the system or application unavailable to legitimate users.

Description OSIDB Bzimport 2026-02-24 02:02:33 UTC
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to version 7.1.2-15, a memory leak exists in `coders/ashlar.c`. The `WriteASHLARImage` allocates a structure.  However, when an exception is thrown, the allocated memory is not properly released, resulting in a potential memory leak. Version 7.1.2-15 contains a patch.
