Microsoft » Windows 2000 : Security Vulnerabilities, CVEs, Published In 2004 (Denial of service) CVSS score >= 8

Buffer overflow in Microsoft Internet Explorer and Explorer on Windows XP SP1, WIndows 2000, Windows 98, and Windows Me may allow remote malicious servers to cause a denial of service (application crash) and possibly execute arbitrary code via long share names, as demonstrated using Samba.

The Windows Internet Naming Service (WINS) for Microsoft Windows Server 2003, and possibly Windows NT and Server 2000, does not properly validate the length of certain packets, which allows attackers to cause a denial of service and possibly execute arbitrary code.
