No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

A security issue exists within Arena® Simulation due to a memory corruption vulnerability in the model.exe (Siman) component. The vulnerability stems from improper validation of user-supplied data, which can result in an out-of-bounds write. An attacker could leverage this vulnerability to execute arbitrary code in the context of the current process by convincing a user to open a malicious file.
