Code execution via crafted printer data
Published Feb 14, 2023 · Updated Aug 19, 2026
Remote code execution in Microsoft PostScript and PCL6 Class Printer Driver allows local users to execute code via crafted printer data. Microsoft has not publicly identified the affected parser routine or the numeric operation mishandling attacker-controlled PostScript or PCL6 data. Low-privileged local access is required, and successful exploitation can execute code in the driver's security context.
