DoS in Win 2000 and XP

by Ivana Strahija on November 18th, 2005 Microsoft has issued an advisory warning users about a newly disclosed denial-of-service vulnerability in Windows 2000 Service Pack 4 and Windows XP Service Pack 1.

The company had to issue the advisory because of reported proof-of-concept code that seeks to exploit the flaw: -Microsoft is concerned that this new report of a vulnerability in Windows 2000 Service Pack 4 and Windows XP Service Pack 1 was not disclosed responsibly, potentially putting computer users at risk.’

The advisory added that Microsoft is currently not aware of any attacks that have resulted from the exploit code. -Microsoft is actively monitoring this situation to keep customers informed and to provide customer guidance as necessary, the company said.

In the meantime, companies need to ensure that their systems are properly updated and have all recommended patches installed, Microsoft said.

The advisory states: -On Windows XP Service Pack 1, an attacker must have valid log-on credentials to try to exploit this vulnerability. The vulnerability could not be exploited remotely by anonymous users. However, the affected component is available remotely to users who have standard user accounts. Customers who have installed Windows XP Service Pack 2 are not affected by this vulnerability. Additionally, customers running Windows Server 2003 and Windows Server 2003 Service Pack 1 are not affected by this vulnerability.’
