FFmpeg through 9.0.2 contains a heap buffer overflow in the GIF encoder's gif image write image() in libavcodec/gif.c because shrunk buf is sized from the first frame's linesize. Attackers can supply PAL8 video whose frame linesize grows mid-stream, causing remap frame to palette() to write past shrunk buf and corrupt the heap during GIF transcoding.
