Microsoft » Windows 2000 : Security Vulnerabilities, CVEs, Published In 2000 (Denial of service)

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.

Microsoft Windows 2000 allows local users to cause a denial of service by corrupting the local security policy via malformed RPC traffic, aka the "Local Security Policy Corruption" 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.

Windows 2000 Telnet Server allows remote attackers to cause a denial of service by sending a continuous stream of binary zeros, which causes the server to crash.

Windows 2000 Server allows remote attackers to cause a denial of service by sending a continuous stream of binary zeros to various TCP and UDP ports, which significantly increases the CPU utilization.

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.

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.

Microsoft TCP/IP Printing Services, aka Print Services for Unix, allows an attacker to cause a denial of service via a malformed TCP/IP print request.
