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

Windows Internet Naming Service (WINS) allows remote attackers to cause a denial of service (connectivity loss) or steal credentials via a 1Ch registration that causes WINS to change the domain controller to point to a malicious server. NOTE: this problem may be limited when Windows 95/98 clients are used, or if the primary domain controller becomes unavailable.
