Description
FFmpeg through 9.0.2 contains an uninitialized memory disclosure vulnerability in libavcodec/tiertexseqv.c that allows attackers to leak stack contents by triggering failed RLE unpacking. Attackers can supply a crafted Tiertex SEQ file so seq_decode_op1() copies an uninitialized 64-byte stack block into decoded frames, exposing stack memory in visible output.
