Microsoft has released a patch for the pre-beta Windows 7
Security sites around the web reported on a out-of-cycle patch that Microsoft would release on October 23 that would fix a security vulnerability affecting most Windows operating systems. The vulnerability was rated critical on Windows XP, Windows 2000 and Windows 2003 and important on Windows Vista, Windows Server 2008 and Windows 7. According to Tech Herald security editor Steve Ragan the vulnerability exploits the Server service which is enabled by default on the operating systems where it was rated critical. The vulnerability could be triggered on unpatched systems by sending a malicious RPC request to the target system.
Windows Vista, Windows Server 2008 and Windows 7 require authentication and the vulnerability has therefore been rated as important on those systems. http://windows7news.com/2008/10/23/f...ws-7-pre-beta/
