CVE-2025-32460

Local unspecified impact via JXL heap over-read

Published Apr 9, 2025 · Updated Apr 9, 2025

Heap-based buffer over-read in GraphicsMagick before 8e56520 allows local users to trigger unspecified impact via a crafted JXL file. ReadJXLImage passes decoded pixel data to ImportViewPixelArea, which reads beyond its heap buffer; the exact mismatched dimension is undisclosed. Reachability requires local processing of the crafted file in a build compiled with JPEG XL support.
