CVE-2026-118753
FreeImage through 3.18.0 and danoli3 fork before 3.19.25 Heap Buffer Overflow via GIF_PLAYBACK Compositing
FreeImage through 3.18.0 and the danoli3 FreeImage fork before 3.19.25 contain a heap buffer overflow vulnerability in PluginGIF.cpp that allows attackers to write past the canvas allocation via unclipped GIF frame rectangles. Attackers can craft a GIF whose frame left plus width exceeds the logical screen width, causing GifPlaybackCompositeFrame() and GifPlaybackFillRect() to corrupt heap memory when loaded with GIF_PLAYBACK.
