Microsoft » Windows 98se : Security Vulnerabilities, CVEs, Published In 2001

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.

Universal Plug and Play (UPnP) on Windows 98, 98SE, ME, and XP allows remote attackers to cause a denial of service via (1) a spoofed SSDP advertisement that causes the client to connect to a service on another machine that generates a large amount of traffic (e.g., chargen), or (2) via a spoofed SSDP announcement to broadcast or multicast addresses, which could cause all UPnP clients to send traffic to a single target system.

Buffer overflow in Universal Plug and Play (UPnP) on Windows 98, 98SE, ME, and XP allows remote attackers to execute arbitrary code via a NOTIFY directive with a long Location URL.

Universal Plug and Play (UPnP) in Windows 98, 98SE, ME, and XP allows remote attackers to cause a denial of service (memory consumption or crash) via a malformed UPnP request.

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.
