Description
FFmpeg through 9.0.2 contains an integer overflow vulnerability in dng_decode_tiles() that allows attackers to leak uninitialized memory via crafted DNG tile dimensions. Attackers can set TileWidth or TileLength near INT_MAX so the tile loop never runs, outputting a frame exposing uninitialized or stale heap memory.
