PYSEC-2026-3493 Pillow: Out-of-bounds read via attacker-controlled row stride on Pillow's mmap path (McIdas AREA files)

Summary When Pillow loads an uncompressed image whose tile uses the raw codec and a mode in Image.MAPMODES, and the image was opened from a filename, it memory-maps the file and builds the image's row pointers directly into the mapping via PyImagingMapBuffer src/map.c. The per-row spacing stride ...
