Descriptions

The server in Microsoft Active Directory on Windows Server 2003 SP2 does not properly handle an update request for a service principal name (SPN), which allows remote attackers to cause a denial of service (authentication downgrade or outage) via a crafted request that triggers name collisions, aka "Active Directory SPN Validation Vulnerability."

El servidor de Microsoft Active Directory en Windows Server 2003 Service Pack 2 no controla correctamente una solicitud de actualización de un nombre principal de servicio (SPN), lo que permite a atacantes remotos provocar una denegación de servicio (degradación de autenticación o corte) a través de una petición manipulada que dispara colisiones de nombre, también conocido como "Vulnerabilidad de Validación SPN de Directorio Activo."
