**Name of the Vulnerable Software and Affected Versions** OPC UA Legacy Java Stack versions prior to 6f176f2 **Description** The issue allows an attacker to block OPC UA server applications via uncontrolled resource consumption, causing them to be unable to serve client applications. This is a denial-of-service vulnerability that can be exploited to exhaust resources. **Recommendations** For versions prior to 6f176f2, update to a version that includes the fix for this issue to prevent resource exhaustion attacks. As a temporary workaround, consider implementing measures to limit resource consumption by the OPC UA server application.
