Microsoft » Windows 2000 : Security Vulnerabilities, CVEs, Published In 2001

Buffer overflow in Microsoft Phone Book Service allows local users to execute arbitrary commands, aka the "Phone Book Service Buffer Overflow" vulnerability.

Buffer overflow in Windows 2000 event viewer snap-in allows attackers to execute arbitrary commands via a malformed field that is improperly handled during the detailed view of event records.

Buffer overflow in Internet Printing ISAPI extension in Windows 2000 allows remote attackers to gain root privileges via a long print request that is passed to the extension through IIS 5.0.

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.

Microsoft Data Access Component Internet Publishing Provider 8.103.2519.0 and earlier allows remote attackers to bypass Security Zone restrictions via WebDAV 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.

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.

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.

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).

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.

Macintosh clients, when using NT file system volumes on Windows 2000 SP1, create subdirectories and automatically modify the inherited NTFS permissions, which may cause the directories to have less restrictive permissions than intended.

Network Dynamic Data Exchange (DDE) in Windows 2000 allows local users to gain SYSTEM privileges via a "WM_COPYDATA" message to an invisible window that is running with the privileges of the WINLOGON process.

The "Configure Your Server" tool in Microsoft 2000 domain controllers installs a blank password for the Directory Service Restore Mode, which allows attackers with physical access to the controller to install malicious programs, aka the "Directory Service Restore Mode Password" 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 first of two variants of this vulnerability.

Telnet Service for Windows 2000 Professional does not properly terminate incomplete connection attempts, which allows remote attackers to cause a denial of service by connecting to the server and not providing any input.

Web Extender Client (WEC) in Microsoft Office 2000, Windows 2000, and Windows Me does not properly process Internet Explorer security settings for NTLM authentication, which allows attackers to obtain NTLM credentials and possibly obtain the password, aka the "Web Client NTLM Authentication" vulnerability.

Remote Data Protocol (RDP) in Windows 2000 Terminal Service does not properly handle certain malformed packets, which allows remote attackers to cause a denial of service, aka the "Invalid RDP Data" vulnerability.

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.

Memory leak in Microsoft 2000 domain controller allows remote attackers to cause a denial of service by repeatedly connecting to the Kerberos service and then disconnecting without sending any data.

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.

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

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.
