Pillow: TIFF encoder ColorMap plane-size mismatch causes a heap out-of-bounds read

Summary A small attacker-supplied TIFF can be opened and loaded normally, then reach an out-of-bounds read when an application saves it back to TIFF with retained metadata. The fixed reproducer is a 1×1, 16-bit grayscale, PackBits-compressed TIFF containing tag 320 ColorMap with 768 SHORT values:...
