FFmpeg through 9.0.2 contains a heap buffer overflow vulnerability in liboapve_encode() in libavcodec/liboapvenc.c that allows attackers to corrupt heap memory by supplying frames larger than the configured encoder dimensions. Attackers can craft videos whose resolution changes mid-stream so that transcoding to APV without rescaling writes attacker-controlled pixel data past the imgb plane buffers.
