CVE-2023-35324

Memory disclosure via printer-driver buffer over-read

Published Jul 11, 2023 · Updated Feb 28, 2025

Buffer over-read in Microsoft PostScript and PCL6 Class Printer Drivers allows local users to disclose sensitive memory contents. The affected drivers read beyond an intended memory buffer boundary; Microsoft has not disclosed the affected routine or triggering input structure. A low-privilege local account is required, and successful exploitation exposes memory without modifying data or interrupting service.
