Ffmpeg: ffmpeg: heap buffer overflow in tdsc_load_cursor() via cur_fmt_mono cursor
A flaw was found in FFmpeg. The tdsc_load_cursor() function writes beyond the bounds of a heap-allocated buffer when processing crafted TDSC cursor data. A remote attacker could exploit this by supplying a specially crafted video file, potentially leading to a denial of service or arbitrary code execution.
