CVE-2023-1709

Code execution via corrupted PDF font parsing

Published Jun 7, 2023 · Updated Jan 6, 2025

Stack-based buffer overflow in APDFL.dll in affected Datalogics and Siemens products allows attackers to execute code via a crafted PDF. While rendering a document containing a corrupted font, the APDFL parser writes beyond a stack buffer and corrupts process memory. Exploitation requires a user to open the malicious file; successful exploitation runs code in the application's process, while unsuccessful attempts can crash it.
