Apple Remote Desktop Client 1.2.4 executes a GUI application as root when it is started by an Apple Remote Desktop Administrator application, which allows remote authenticated users to execute arbitrary code when loginwindow is active via Fast User Switching.

The local and remote desktop login screens in Microsoft Windows XP before SP2 and 2003 allow remote attackers to cause a denial of service (CPU and memory consumption) by repeatedly using the WinKey+"U" key combination, which causes multiple copies of Windows Utility Manager to be loaded more quickly than they can be closed when the copies detect that another instance is running.

pGina 1.7.6 and possibly older versions, when the Restart or Shutdown options are enabled on the login screen, allows remote attackers to cause a denial of service by connecting via Remote Desktop and clicking restart or shutdown.

The Remote Data Protocol (RDP) version 5.1 in Microsoft Windows XP allows remote attackers to cause a denial of service (crash) when Remote Desktop is enabled via a PDU Confirm Active data packet that does not set the Pattern BLT command, aka "Denial of Service in Remote Desktop."

The Remote Desktop Sharing (RDS) Screen Saver Protection capability for Microsoft NetMeeting 3.01 through SP2 (4.4.3396) allows attackers with physical access to hijack remote sessions by entering certain logoff or shutdown sequences (such as CTRL-ALT-DEL) and canceling out of the resulting user confirmation prompts, such as when the remote user is editing a document.

The Remote Desktop client in Windows XP sends the most recent user account name in cleartext, which could allow remote attackers to obtain terminal server user account names via sniffing.

Terminal Server in Windows NT and Windows 2000 allows remote attackers to cause a denial of service via a sequence of invalid Remote Desktop Protocol (RDP) packets.

Memory leak in Terminal servers in Windows NT and Windows 2000 allows remote attackers to cause a denial of service (memory exhaustion) via a large number of malformed Remote Desktop Protocol (RDP) requests to port 3389.

McAfee Remote Desktop 3.0 and earlier allows remote attackers to cause a denial of service (crash) via a large number of packets to port 5045.

Microsoft NetMeeting 3.01 with Remote Desktop Sharing enabled allows remote attackers to cause a denial of service via a malformed string to the NetMeeting service port, aka a variant of the "NetMeeting Desktop Sharing" vulnerability.
