A security flaw that could let an attacker remotely crash computers running Windows exists in several versions of the operating system, not just Windows XP.
Windows 2000, Windows XP and Windows Server 2003 are vulnerable to a denial-of-service attack that exploits a problem in the Remote Desktop Protocol, Microsoft said in an advisory on Saturday.
RDP is a protocol that enables remote access to Windows systems. Because of a flaw in the way Windows handles remote desktop requests, an attacker could crash a PC by sending a malformed remote request, Microsoft said. The advisory was released after the security researcher who discovered the flaw last week flagged Windows XP as vulnerable. Microsoft confirmed the issue on Friday and published the advisory over the weekend.
