CVE-2026-42169

A heap-buffer-overflow vulnerability exists in the APNG (Animated PNG) file loader of GIMP. This flaw occurs when the fcTL width exceeds the IHDR width, leading to pixel data being written past the end of a heap allocation. Additionally, a heap-based buffer overflow exists in the DDS plug-in due to a BPP mismatch in the loadlayer() function. Both vulnerabilities can be triggered by opening a specially crafted image file, potentially leading to code execution.
