Windows 2000 allows remote attackers to cause a denial of service (CPU consumption) by flooding Internet Key Exchange (IKE) UDP port 500 with packets that contain a large number of dot characters.

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.

Terminal Services Manager MMC in Windows 2000 and XP trusts the Client Address (IP address) that is provided by the client instead of obtaining it from the packet headers, which allows clients to spoof their public IP address, e.g. through a Network Address Translation (NAT).

Vulnerabilities in RPC servers in (1) Microsoft Exchange Server 2000 and earlier, (2) Microsoft SQL Server 2000 and earlier, (3) Windows NT 4.0, and (4) Windows 2000 allow remote attackers to cause a denial of service via malformed inputs.

Memory leak in NNTP service in Windows NT 4.0 and Windows 2000 allows remote attackers to cause a denial of service (memory exhaustion) via a large number of malformed posts.

Buffer overflow in IrDA driver providing infrared data exchange on Windows 2000 allows attackers who are physically close to the machine to cause a denial of service (reboot) via a malformed IrDA packet.

By default, DNS servers on Windows NT 4.0 and Windows 2000 Server cache glue records received from non-delegated name servers, which allows remote attackers to poison the DNS cache via spoofed DNS responses.

Vulnerability in authentication process for SMTP service in Microsoft Windows 2000 allows remote attackers to use incorrect credentials to gain privileges and conduct activities such as mail relaying.

Windows 2000 and Windows NT allows local users to cause a denial of service (reboot) by executing a command at the command prompt and pressing the F7 and enter keys several times while the command is executing, possibly related to an exception handling error in csrss.exe.

Windows 2000 domain controller in Windows 2000 Server, Advanced Server, or Datacenter Server allows remote attackers to cause a denial of service via a flood of malformed service requests.

Buffer overflow in Microsoft Visual Studio RAD Support sub-component of FrontPage Server Extensions allows remote attackers to execute arbitrary commands via a long registration request (URL) to fp30reg.dll.

Microsoft Windows 2000 telnet service allows attackers to prevent idle Telnet sessions from timing out, causing a denial of service by creating a large number of idle sessions.

Handle leak in Microsoft Windows 2000 telnet service allows attackers to cause a denial of service by starting a large number of sessions and terminating them.

Information disclosure vulnerability in Microsoft Windows 2000 telnet service allows remote attackers to determine the existence of user accounts such as Guest, or log in to the server without specifying the domain name, via a malformed userid.

Microsoft Windows 2000 telnet service allows attackers to cause a denial of service (crash) via a long logon command that contains a backspace.

Microsoft Windows 2000 telnet service creates named pipes with predictable names and does not properly verify them, which allows local users to execute arbitrary commands by creating a named pipe with the predictable name and associating a malicious program with it, the first of two variants of this vulnerability.

Microsoft Windows 2000 telnet service creates named pipes with predictable names and does not properly verify them, which allows local users to execute arbitrary commands by creating a named pipe with the predictable name and associating a malicious program with it, the second of two variants of this vulnerability.

Microsoft Windows 2000 telnet service allows a local user to make a certain system call that allows the user to terminate a Telnet session and cause a denial of service.

Running Windows 2000 LDAP Server over SSL, a function does not properly check the permissions of a user request when the directory principal is a domain user and the data attribute is the domain password, which allows local users to modify the login password of other users.

The change password option in the Windows Security interface for Windows 2000 allows attackers to use the option to attempt to change passwords of other users on other systems or identify valid accounts by monitoring error messages, possibly due to a problem in the NetuserChangePassword function.
