Summary

This security update resolves a privately reported vulnerability in Windows. The vulnerability could allow denial of service on Internet Authentication Service (IAS) or Network Policy Server (NPS) if an attacker sends specially crafted username strings to IAS or NPS. Although the denial of service vulnerability would not allow an attacker to execute code or to elevate user rights, it could prevent Remote Authentication Dial-in User Service (RADIUS) authentication on IAS or NPS.
