GHSA-VPXV-R9PG-7GPR ImageMagick has Global Buffer Overflow (OOB Read) via Negative Pixel Index in UIL and XPM Writer

The UIL and XPM image encoder do not validate the pixel index value returned by GetPixelIndex before using it as an array subscript. In HDRI builds, Quantum is a floating-point type, so pixel index values can be negative. An attacker can craft an image with negative pixel index values to trigger ...

CVE-2026-25898

ImageMagick (UIL/XPM encoders) is affected by CVE-2026-25898. In HDRI builds, Quantum is a floating-point type, so the pixel index value returned by GetPixelIndex() can be negative. The UIL and XPM image encoders may use this negative value as an array subscript without proper validation, enablin...

CVE-2026-25898 Imagemagick Has Global Buffer Overflow (OOB Read) via Negative Pixel Index in UIL and XPM Writer

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-15 and 6.9.13-40, the UIL and XPM image encoder do not validate the pixel index value returned by GetPixelIndex before using it as an array subscript. In HDRI builds, Quantum is ...
