CVE-2004-0567: Microsoft Windows 2000

High severity, CVSS 7.5. EPSS: 68.7% chance of exploitation in the next 30 days.

The Windows Internet Naming Service (WINS) in Windows NT Server 4.0 SP 6a, NT Terminal Server 4.0 SP 6, Windows 2000 Server SP3 and SP4, and Windows Server 2003 does not properly validate the computer name value in a WINS packet, which allows remote attackers to execute arbitrary code or cause a denial of service (server crash), which results in an "unchecked buffer" and possibly triggers a buffer overflow, aka the "Name Validation Vulnerability."

Affected products

• Microsoft Windows 2000: any version
• Microsoft Windows 2003 Server: version 64-bit only; version r2 only
• Microsoft Windows Nt: version 4.0 only
