FFmpeg through 9.0.2 contains an out-of-bounds heap read vulnerability in tdsc_load_cursor() in libavcodec/tdsc.c, which stores cursor dimensions before validating them. Attackers can supply a crafted AVI file with oversized TDSC cursor dimensions so tdsc_paint_cursor() reads past the cursor buffer, crashing the decoder or leaking heap memory into frames.
FFmpeg <= 9.0.2Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
