These vulnerabilities also affects JT Utilities before V13.1.1.0. If a user is tricked to open a malicious JT file with any of the affected products, this could lead the application to crash or potentially lead to arbitrary code execution.\n\nSiemens recommends to update to the latest versions and to limit opening of untrusted files from unknown sources in the affected products."
