Authenticated code execution via printer-driver heap overflow
Published Mar 14, 2023 · Updated Feb 28, 2025
Heap-based buffer overflow in Microsoft Windows PostScript and PCL6 printer drivers allows remote authenticated users to execute code. Microsoft identifies the affected driver classes and heap corruption category but has not published the parsing routine or malformed field that causes the overwrite. Exploitation requires network access and low privileges; successful abuse executes code on the target, while public records do not disclose the resulting process context.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
