CVE-2004-0567

High
Published: Translated: NVD NIST

Summary

A vulnerability in the Windows Internet Naming Service (WINS) allows a remote attacker to execute arbitrary code or cause a denial of service (server crash) by sending a specially crafted WINS packet with an improperly validated computer name. The issue results from an unchecked buffer, potentially leading to a buffer overflow.

Risk Assessment

An attacker can remotely take control of the WINS server or cause it to crash, potentially disrupting naming services in the network and affecting the availability of systems dependent on WINS.

Recommendation

Apply the appropriate security patches provided by the vendor immediately for all affected Windows versions. Where possible, restrict access to the WINS service to trusted hosts only.

Original NVD description (English source)

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."
