Descriptions

ncp in Novell eDirectory before 8.7.3 SP9, and 8.8.x before 8.8.1 FTF2, does not properly handle NCP fragments with a negative length, which allows remote attackers to cause a denial of service (daemon crash) when the heap is written to a log file.

ncp en Novell eDirectory anterior a 8.7.3 SP9, y 8.8.x anterior a 8.8.1 FTF2, no maneja adecuadamente fragmentos NCP con una longitud negativa, lo cual permite a atacantes remotos provocar una denegación de servicio (caída del demonio) cuando el montón se escribe a un fichero de registro de eventos.
