FFmpeg through 9.0.2 contains a heap buffer overflow vulnerability in libavcodec/flicvideo.c that allows attackers to write out of bounds because check_pixel_ptr() checks only one bound with negative-stride frames. Attackers can supply a crafted FLIC file whose RLE and delta chunks write pixel data past frame storage, corrupting heap memory to crash applications or possibly execute code.
