CVE-2025-55004

ImageMagick: heap-buffer overflow read in MNG magnification with alpha

Published: 8/13/2025 Last updated: 8/13/2025 Reserved: 8/4/2025

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to version 7.1.2-1, ImageMagick is vulnerable to heap-buffer overflow read around the handling of images with separate alpha channels when performing image magnification in ReadOneMNGIMage. This can likely be used to leak subsequent memory contents into the output image. This issue has been patched in version 7.1.2-1.
