Pillow tiled-TIFF decoder reads past tile buffer in copy4 (Unpack.c:1290)
影響: pip:pillow >= 8.2.0, < 13.0.0 → 13.0.0 Summary Pillow's libImaging _decodeTile decoder, used to decode tiled TIFF images, allocates a per-tile buffer using realloc(state->buffer, TIFFTileSize(tiff)). After each TIFFReadTile it then iterates tile_y from 0 up to current_tile_length and calls the configured row unpacker (here copy4) with the source pointer state->buffer + tile_y row_byte_size. When libtiff returns a tile_bytes_size smaller than the worst-case row_byte_size tile_length, the inner stride-and-copy loop walks past the real…
