Summary
JT Open Toolkit (JTTK) before V10.8.1.1 contains multiple vulnerabilities that could be triggered when it reads a maliciously crafted JT file. These vulnerabilities also affects JT Utilities before V12.8.1.1. If a user is tricked to open a malicious file with any of the affected products, this could lead the application to crash or potentially lead to arbitrary code execution.
Siemens recommends to update to the latest versions and to limit opening of untrusted files from unknown sources in the affected products.
