Microsoft Security Update MS13-064 and DirectAccess

With the August security update release cycle, Microsoft issued security bulletin MS13-064 to address a vulnerability in the Windows NAT driver that could result in a denial of service. The vulnerability could be exploited by an attacker who sends a specially crafted ICMP packet to the server running the Windows NAT Driver service. The vulnerability exists only on Windows Server 2012 and the affected driver, winnat.sys, is present when the DirectAccess role is installed. This vulnerability only affects only full installations of Windows Server 2012. Windows Server 2012 Core is not affected. If you are running DirectAccess on a full installation of Windows Server 2012, make sure you install this update as soon as possible to be protected from potential denial of service attacks. For more information about this update, click here. For a comprehensive list of updates that apply to DirectAccess on Windows Server 2012 as well as previous versions, please refer to Jason Jones’ DirectAccess hotfix summary page.
