CVE-2023-7066

Code execution via APDFL out-of-bounds read

Published Aug 12, 2024 · Updated Aug 27, 2025

Out-of-bounds read in APDFL in Siemens Teamcenter Visualization and JT2Go allows attackers to execute code through a crafted PDF. The embedded APDFL parser reads past the end of an allocated structure while processing the malicious file. Exploitation requires a user to open the PDF; successful memory misuse runs code in the current process, while an unsuccessful attempt can crash the application.
