Description
A memory buffer vulnerability in Rockwell Automation Arena Simulation could potentially let a threat actor read beyond the intended memory boundaries. This could reveal sensitive information and even cause the application to crash, resulting in a denial-of-service condition. To trigger this, the user would unwittingly need to open a malicious file shared by the threat actor.
