**Name of the Vulnerable Software and Affected Versions** RealVNC versions 4.0 and earlier **Description** The issue allows remote attackers to cause a denial of service, resulting in a crash, by establishing a large number of connections to the "port 5900" endpoint. **Recommendations** For RealVNC versions 4.0 and earlier, consider restricting access to port 5900 to minimize the risk of exploitation.
