Microsoft, which is working on a patch, suggests users block TCP port 3389 on their firewalls, disable Terminal Services or Remote Desktop if not required, or secure remote desktop connections using either Internet Protocol Security or a virtual private network connection until a patch is ready.
There have not been any reported attacks seeking to exploit this vulnerability, the company said.
