Local memory disclosure via printer-driver buffer over-read
Published Jul 11, 2023 · Updated Feb 28, 2025
Buffer over-read in the Microsoft PostScript and PCL6 Class Printer Driver on affected Windows releases allows local users to read memory. The driver reads beyond a buffer boundary while handling an undisclosed local input; Microsoft has not published the precise parser or buffer operation. Low-privileged local access is required, and the reported consequence is limited to memory disclosure without data modification or service interruption.
