CVE-2023-38532

Denial of service via X_T stack exhaustion

Published Aug 8, 2023 · Updated Nov 25, 2024

Stack exhaustion in Siemens Parasolid and Teamcenter Visualization allows attackers to interrupt service via a crafted X_T file. The X_T parser exhausts the process stack while handling attacker-controlled model data, making the current application process unavailable. Exploitation requires a user to open an untrusted X_T file; the vendor reports no confidentiality or integrity impact.
