Large input\nvalues can cause these calculations to wrap around before the resulting\ncoordinates are passed to SetOverlayViewPort().\n\nSetOverlayViewPort() packs the viewport coordinates into 16-bit\nregister fields. The X coordinates are additionally adjusted by +2\nand +1 before being written. Validate the coordinate calculations\nfor 32-bit wraparound and ensure that the adjusted coordinates fit\nwithin their 16-bit register fields before calling\nSetOverlayViewPort().\n\nFound by Linux
