Microsoft RDP Server shipped with Windows XP is vulnerable to a denial of service attack. This attack does not require that the client be authenticated with the RDP server because the attack happens in the negotiation before the drawing of the login screen. This vulnerability is present in Microsoft RDP 4.0, 5.0 and 5.1. It affects Windows XP and Windows .NET Standard Server Beta 3.
The Microsoft Windows XP Professional Remote Desktop implementation is prone to a denial of service. It is possible for a malicious client to trigger this condition by sending a maliciously crafted packet to the vulnerable host during the negotiation of client/server graphics capabilities. Clients may specify drawing commands based on what is supported. If the Pattern BLT command is specified in a packet, Microsoft Windows XP Professional will crash when it tries to render the pattern. This issue also exists in Microsoft Windows .NET Standard Server Beta 3.
