Executive brief
ImageMagick, a widely used software suite for image processing, contains a flaw in how it handles certain image conversions. When the software fails to write a Multiple-image Network Graphics (MNG) file using its PNG encoder, it may fail to release system memory. Over time, repeated exploitation or accidental triggers could lead to increased memory consumption, potentially slowing down or crashing services that rely on this library.
Technical details
A memory leak (CWE-401) exists in ImageMagick's PNG encoder component. The vulnerability is triggered when the encoder encounters a failure while attempting to write a Multiple-image Network Graphics (MNG) image. Under these specific error conditions, the application fails to release previously allocated memory. While the attack complexity is high and the impact is limited to a low reduction in availability, persistent exploitation could lead to denial-of-service through memory exhaustion. The issue is addressed in Magick.NET version 14.12.0.
