CVE-2026-25898

A flaw was found in ImageMagick. A remote attacker can exploit this vulnerability by crafting a malicious image file. The UIL and XPM image encoders do not properly validate pixel index values, which can become negative in High Dynamic Range Imaging (HDRI) builds. This improper validation leads to a global buffer overflow read, potentially resulting in information disclosure or a denial of service (DoS) due to a process crash.

This MODERATE impact vulnerability in ImageMagick's UIL and XPM image encoders allows for a global buffer overflow read when processing specially crafted images with negative pixel index values. This flaw can lead to information disclosure or a denial of service. Red Hat Enterprise Linux and Community Projects that include ImageMagick are affected.
