Pillow is a Python imaging library. From 8.2.0 until 13.0.0, Pillow's tiled-TIFF decoder can read past the tile buffer while copying four-byte pixels. In _decodeTile, libtiff can return a tile allocation smaller than the required row stride multiplied by the tile length, and Pillow's stride-and-copy loop walks beyond that allocation. An attacker can supply a crafted tiled TIFF to an application that loads it. This can expose adjacent heap data in pixels or crash the process. This issue is fixed in version 13.0.0.
