From: Archana Polampalli <[email protected]> FFmpeg version n6.1 was discovered to contain a heap buffer overflow vulnerability in the draw_block_rectangle function of libavfilter/vf_codecview.c. This vulnerability allows attackers to cause undefined behavior or a Denial of Service (DoS) via crafted input.
