CVE-2026-54604 OpenSlide: openslide_read_region() returns uninitialized memory with libtiff 4.7.1

OpenSlide is a C library for reading whole slide image files. Prior to 4.0.1, a behavior change in libtiff 4.7.1 causes the indirect TIFF tile path in src/openslide-decode-tiff.c and openslidetiffreadtile to request a full-height destination for a partial bottom tile row, allowing uninitialized...
