Microsoft Terminal Server, when running an application session with the "Start program at logon" and "Override settings from user profile and Client Connection Manager wizard" options, allows local users to execute arbitrary code by forcing an Explorer error. NOTE: a third-party researcher has stated that the options are "a convenience to users" and were not intended to restrict execution of arbitrary code

Buffer overflow in FileZilla Server Terminal 0.9.4d may allow remote attackers to cause a denial of service (terminal crash) via a long USER ftp command.

Buffer overflow in Microsoft Step-by-Step Interactive Training (orun32.exe) allows remote attackers to execute arbitrary code via a bookmark link file (.cbo, cbl, or .cbm extension) with a long User field.

Microsoft Agent allows remote attackers to spoof trusted Internet content and execute arbitrary code by disguising security prompts on a malicious Web page.

Apple Terminal 1.4.4 allows attackers to execute arbitrary commands via terminal escape sequences.

Remote Data Protocol (RDP) version 5.0 in Microsoft Windows 2000 and RDP 5.1 in Windows XP does not encrypt the checksums of plaintext session data, which could allow a remote attacker to determine the contents of encrypted sessions via sniffing, aka "Weak Encryption in RDP Protocol."

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."

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.

The default permissions for the RAS Administration key in Windows NT 4.0 allows local users to execute arbitrary commands by changing the value to point to a malicious DLL, aka one of the "Registry Permissions" vulnerabilities.

The default permissions for the MTS Package Administration registry key in Windows NT 4.0 allows local users to install or modify arbitrary Microsoft Transaction Server (MTS) packages and gain privileges, aka one of the "Registry Permissions" vulnerabilities.
