Descriptions
The xdrDecodeString function in XNFS.NLM in Novell Netware 6.5 before SP8 allows remote attackers to cause a denial of service (abend) or execute arbitrary code via a crafted, signed value in a NFS RPC request to port UDP 1234, leading to a stack-based buffer overflow.
La función xdrDecodeString en XNFS.NLM en Novell Netware v6.5 anterior a SP8 permite a atacantes remotos provocar una denegación de servicio o ejecutar código arbitrario a través de un valor firmado manipulado en una peticion RPC NFS para el puerto UDP 1234, dando lugar a un desbordamiento de búfer basado en pila.
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Novell Netware. Authentication is not required to exploit this vulnerability.
The flaw exists within the XNFS.NLM component which listens by default on UDP port 1234. When handling the an NFS RPC request the xdrDecodeString function uses a user supplied length value to null terminate a string. This value can be signed allowing the NULL byte to be written at an arbitrary address. A remote attacker can exploit this vulnerability to execute arbitrary code under the context of the system.
