Descriptions

Unspecified vulnerability in the NCP service in Novell eDirectory 8.8.5 before 8.8.5.6 and 8.8.6 before 8.8.6.2 allows remote attackers to cause a denial of service (hang) via a malformed FileSetLock request to port 524.

Vulnerabilidad no especificada en el servicio NPC en Novell eDirectory v8.8.5 anterior a v8.8.5.6 y v8.8.6 anterior a v8.8.6.2, permite a atacantes remotos provocar una denegación de servicio (cuelgue) a través de una petición FileSetLock mal formada al puerto 524.

This vulnerability allows attackers to deny services on vulnerable installations of Novell eDirectory. Authentication is not required in order to trigger this vulnerability.
The flaw exists within Novell's eDirectory Server's NCP implementation. Novell's eDirectory Server binds to port 524 for processing NCP requests. When the application processes a malformed FileSetLock request, the service will become unresponsive resulting in an inability to authenticate to that server.
