Description

FFmpeg versions 3.4 through 8.1.2 contain an out-of-bounds write vulnerability in the vf_floodfill video filter that allows attackers to corrupt heap memory by supplying a dynamically sized video stream with filtergraph reinitialization disabled via -reinit_filter 0. When config_input() allocates the points traversal stack based on initial frame dimensions and a subsequent larger frame is processed, filter_frame() performs flood-fill neighbor pushes beyond the original allocation boundary, resulting in heap corruption and process crash with potential for code execution depending on heap layout and process hardening.
