ImageMagick memory leak in log colorspace transformation

Severity: low · CVSS 2.9 · Published 2026-07-24

Vendors: ImageMagick.

Executive brief

ImageMagick is a software suite used to create, edit, and convert images. A memory leak has been identified when the software fails to transform an image into a specific color format. While the impact is low, repeated failures could gradually consume system memory, potentially slowing down or destabilizing applications that process many images.

Technical details

A memory leak (CWE-401) exists in ImageMagick during color transformation operations. Specifically, when a transformation to the log colorspace fails, the application fails to release previously allocated memory. This is a local vulnerability with high attack complexity, as it requires triggering a specific failure state during image processing. An attacker could potentially cause a minor denial-of-service condition through resource exhaustion if they can repeatedly trigger these failed transformations. The issue is addressed in Magick.NET version 14.15.0.
