FFmpeg through 9.0.2 contains an uncontrolled resource consumption vulnerability in the dts2pts bitstream filter that allows attackers to exhaust CPU through unbounded per-packet POC node allocation. Attackers can supply a crafted H.264 packet with many slices of alternating picture order counts, forcing h264_queue_frame() to allocate tree nodes per slice and deny service.
