Vulnerability Present In Windows XP Media Center Edition
Microsoft is investigating new public reports of a vulnerability in Remote Desktop Services. We have not been made aware of attacks that try to use the reported vulnerability or of customer impact at this time, but we are aggressively investigating the public reports.
Our initial investigation has revealed that a denial of service vulnerability exists that could allow an attacker to send a specially crafted Remote Desktop Protocol (RDP) request to an affected system. Our investigation has determined that this is limited to a denial of service, and therefore an attacker could not use this vulnerability to take complete control of a system. Services that utilize the Remote Desktop Protocol are not enabled by default, however if a service were enabled, an attacker could cause this system to restart.
Note Remote Desktop is enabled by default on Windows XP Media Center Edition.
