Microsoft » Windows Nt : Security Vulnerabilities, CVEs, Published In 2000 CVSS score >= 4

Windows NT 4.0 and Windows 2000 hosts allow remote attackers to cause a denial of service (unavailable connections) by sending multiple SMB SMBnegprots requests but not reading the response that is sent back.

The default configuration for the domain name resolver for Microsoft Windows 98, NT 4.0, 2000, and XP sets the QueryIpMatching parameter to 0, which causes Windows to accept DNS updates from hosts that it did not query, which allows remote attackers to poison the DNS cache.

Interactions between the CIFS Browser Protocol and NetBIOS as implemented in Microsoft Windows 95, 98, NT, and 2000 allow remote attackers to modify dynamic NetBIOS name cache entries via a spoofed Browse Frame Request in a unicast or UDP broadcast datagram.

Buffer overflows in Microsoft Network Monitor (Netmon) allow remote attackers to execute arbitrary commands via a long Browser Name in a CIFS Browse Frame, a long SNMP community name, or a long username or filename in an SMB session, aka the "Netmon Protocol Parsing" vulnerability. NOTE: It is highly likely that this candidate will be split into multiple candidates.

Vulnerability in Microsoft Windows NT 4.0 allows remote attackers to cause a denial of service in IIS by sending it a series of malformed requests which cause INETINFO.EXE to fail, aka the "Invalid URL" vulnerability.

The NetBIOS Name Server (NBNS) protocol does not perform authentication, which allows remote attackers to cause a denial of service by sending a spoofed Name Conflict or Name Release datagram, aka the "NetBIOS Name Server Protocol Spoofing" vulnerability.

The registry entry for the Windows Shell executable (Explorer.exe) in Windows NT and Windows 2000 uses a relative path name, which allows local users to execute arbitrary commands by inserting a Trojan Horse named Explorer.exe into the %Systemdrive% directory, aka the "Relative Shell Path" vulnerability.

Windows NT and Windows 2000 hosts allow a remote attacker to cause a denial of service via malformed DCE/RPC SMBwriteX requests that contain an invalid data length.

The CIFS Computer Browser service allows remote attackers to cause a denial of service by sending a ResetBrowser frame to the Master Browser, aka the "ResetBrowser Frame" vulnerability.

The CIFS Computer Browser service on Windows NT 4.0 allows a remote attacker to cause a denial of service by sending a large number of host announcement requests to the master browse tables, aka the "HostAnnouncement Flooding" or "HostAnnouncement Frame" vulnerability.

The Remote Registry server in Windows NT 4.0 allows local authenticated users to cause a denial of service via a malformed request, which causes the winlogon process to fail, aka the "Remote Registry Access Authentication" vulnerability.

Buffer overflow in Microsoft command processor (CMD.EXE) for Windows NT and Windows 2000 allows a local user to cause a denial of service via a long environment variable, aka the "Malformed Environment Variable" vulnerability.

Windows 95, Windows 98, Windows 2000, Windows NT 4.0, and Terminal Server systems allow a remote attacker to cause a denial of service by sending a large number of identical fragmented IP packets, aka jolt2 or the "IP Fragment Reassembly" vulnerability.

The default permissions for the Cryptography\Offload registry key used by the OffloadModExpo in Windows NT 4.0 allows local users to obtain compromise the cryptographic keys of other users.

Buffer overflows in htimage.exe and Imagemap.exe in FrontPage 97 and 98 Server Extensions allow a user to conduct activities that are not otherwise available through the web site, aka the "Server-Side Image Map Components" vulnerability.

The Windows NT scheduler uses the drive mapping of the interactive user who is currently logged onto the system, which allows the local user to gain privileges by providing a Trojan horse batch file in place of the original batch file.

Windows NT Autorun executes the autorun.inf file on non-removable media, which allows local attackers to specify an alternate program to execute when other users access a drive.

NtImpersonateClientOfPort local procedure call in Windows NT 4.0 allows local users to gain privileges, aka "Spoofed LPC Port Request."

The Cenroll ActiveX control (xenroll.dll) for Terminal Server Editions of Windows NT 4.0 and Windows NT Server 4.0 before SP6 allows remote attackers to cause a denial of service (resource consumption) by creating a large number of arbitrary files on the target machine.

Windows NT Service Control Manager (SCM) allows remote attackers to cause a denial of service via a malformed argument in a resource enumeration request.

After an unattended installation of Windows NT 4.0, an installation file could include sensitive information such as the local Administrator password.

A system does not present an appropriate legal message or warning to a user who is accessing it.
