Surprise, surprise, another XP security flaw. This time, it is a flaw that affects the Windows Remote Desktop Service. Seemingly, this flaw could be used by an attacker to remotely exploit the problem to crash a victim's PC. The user would be affected by a Blue Screen of Death (and I know how you all just love those.)

"The issue was originally privately reported to Microsoft and we are working on an update that will be released when it is of the appropriate quality," a Microsoft representative said. "The concern is that this has now gone public, potentially putting customers at risk."
Fully patched Windows XP machines are vulnerable to this problem; even systems with service pack 2 installed are not safe. Security monitoring company Secunia rates the vulnerability as "moderately critical."
