NRT-0391 Microsoft Adds New Security APIs to VISTA and XP:


Microsoft has added new security-related APIs to upcoming service packs for Windows VISTA and XP to expand the use of the anti-exploit technology dubbed Data Execution Prevention (DEP). The new APIs will be included with VISTA Service Pack 1, Windows XP Service Pack 3, and the brand-new Windows 2008 when those operating systems ship. DEP, which also goes by NX - for No eXecute - was introduced by Microsoft in Windows XP SP2 and expanded in VISTA and Server 2008. It's designed to stop some kinds of exploits - buffer overflow attacks primarily - by blocking code from executing in memory that's supposed to contain only data. The new APIs can be used by developers working with the older ATL to enable DEP at runtime, or when the application actually launches. Previously, those programmers were forced to decide ahead of time whether their software would try to protect itself using DEP. Microsoft has slated VISTA SP1 for release this quarter, though speculation has mounted that it will appear within a matter of weeks. Windows XP SP3 is scheduled to ship sometime in the first half of the year, while Windows Server 2008 has been tagged with a late-February launch date.
