Microsoft security flaw moderate this month

Microsoft Corp. recently issued a security update for a 'Denial of Service' vulnerability that exists in the IDirectPlay4 application programming interface (API) of its DirectPlay, according to a statement on the company's website. "If a user is running a networked DirectPlay application, an attacker who successfully exploits this vulnerability can cause the DirectPlay application to fail," it says.
