Executive brief
ImageMagick is a widely used software suite for displaying, converting, and editing image files. A flaw in how it handles specific image formats (MIFF) can cause the software to leak memory if a system error occurs during processing. While this is a low-risk issue, it could potentially lead to reduced system performance or application crashes if triggered repeatedly.
Technical details
A memory leak vulnerability (CWE-401) exists in the ImageMagick MIFF encoder. The issue is triggered when a memory allocation failure occurs during the encoding process, causing the product to fail to release previously allocated memory. This is a local attack vector with high complexity, as it requires the attacker to influence the environment to cause allocation failures. An exploit results in a minor impact on availability due to resource exhaustion. The vulnerability is patched in Magick.NET version 14.15.0.
