High [CVE-2026-42169] GIMP APNG loader heap-buffer-overflow when fcTL width exceeds IHDR width (file-png.c)
CVE-2026-42169Source published Source updated
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 `load_layer()` function. Both vulnerabilities can be triggered by opening a specially crafted image file, potentially leading to code execution. This vulnerability in GIMP's APNG loader and DDS plug-in could lead to a heap-buffer-overflow when processing specially crafted image files. Exploitation requires a user to open a malicious APNG or DDS image. Red Hat products shipping GIMP are affected if users are exposed to untrusted image files. Red Hat severity: Moderate…
