CVE-2023-24929Network attack vector

Authenticated code execution via undisclosed type confusion

Published Apr 11, 2023 · Updated Feb 28, 2025

Type confusion in Microsoft's PostScript and PCL6 Class Printer Driver allows remote authenticated users to execute code on affected Windows systems. Microsoft identifies incompatible-type resource access but does not disclose the parsing locus or untrusted value that receives the wrong type. Network access with low privileges is required, and successful exploitation permits arbitrary code execution affecting host data and availability.
