BIT-PILLOW-2026-59199 Pillow: Heap out-of-bounds write `Image.paste()` / `Image.crop()` via signed coordinate overflow

Pillow is a Python imaging library. Prior to 12.3.0, Pillow public image coordinate APIs can trigger a native heap out-of-bounds write when given coordinates near the signed 32-bit integer limits in Image.paste, Image.crop, or Image.alphacomposite. This issue is fixed in version 12.3.0...

GHSA-5QV7-J6W5-FR4M imageproc has fragile bounds check when sampling from image

A read of pixels was coded as modifying coordinates to lie within the image bounds. It would calculate a coordinate by adding a constant to an input and taking the minimum of the resulting coordinate and 'dimension - 1'. This would not protect against malicious inputs that could overflow the...
