The Microsoft Windows network stack allows remote attackers to cause a denial of service (CPU consumption) via a flood of malformed ARP request packets with random source IP and MAC addresses, as demonstrated by ARPNuke.

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

Various TCP/IP stacks and network applications allow remote attackers to cause a denial of service by flooding a target host with TCP connection attempts and completing the TCP/IP handshake without maintaining the connection state on the attacker host, aka the "NAPTHA" class of vulnerabilities. NOTE: this candidate may change significantly as the security community discusses the technical nature of NAPTHA and learns more about the affected applications. This candidate is at a higher level of abstraction than is typical for CVE.

NMPI (Name Management Protocol on IPX) listener in Microsoft NWLink does not properly filter packets from a broadcast address, which allows remote attackers to cause a broadcast storm and flood the network.

File and Print Sharing service in Windows 95, Windows 98, and Windows Me does not properly check the password for a file share, which allows remote attackers to bypass share access controls by sending a 1-byte password that matches the first character of the real password, aka the "Share Level Password" vulnerability.

NETBIOS client in Windows 95 and Windows 98 allows a remote attacker to cause a denial of service by changing a file sharing service to return an unknown driver type, which causes the client to crash.

The web-based folder display capability in Microsoft Internet Explorer 5.5 on Windows 98 allows local users to insert Trojan horse programs by modifying the Folder.htt file and using the InvokeVerb method in the ShellDefView ActiveX control to specify a default execute option for the first file that is listed in the folder.

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.

Microsoft Windows 9x operating systems allow an attacker to cause a denial of service via a pathname that includes file device names, aka the "DOS Device in Path Name" vulnerability.

Multihomed Windows systems allow a remote attacker to bypass IP source routing restrictions via a malformed packet with IP options, aka the "Spoofed Route Pointer" vulnerability.
