Windows 2000

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.Show less

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.Show less

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.Show less

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.Show less

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.Show less

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.Show less

Task Manager in Windows 2000 does not allow local users to end processes with uppercase letters named (1) winlogon.exe, (2) csrss.exe, (3) smss.exe and (4) services.exe via the Process tab which could allow local users to install Trojan horses that cannot be stopped with the Task Manager.Show less

Multiple TCP implementations could allow remote attackers to cause a denial of service (bandwidth and CPU exhaustion) by setting the maximum segment size (MSS) to a very small number and requesting large amounts of data, which generates more packets with less TCP-level data that amplify network traffic and consume more server CPU to process.Show less
