Tecnomatix Plant Simulation contains a type confusion vulnerability that could be triggered when the application reads MODEL files. If a user is tricked to open a malicious file using the affected application, this could lead to a crash, and potentially also to arbitrary code execution on the target host system.
Siemens has released new versions for the affected products and recommends to update to the latest versions.
