Summary
OpenDJ is an LDAPv3 compliant directory service. OpenDJ prior to 4.9.3 contains a denial-of-service (DoS) vulnerability that causes the server to become unresponsive to all LDAP requests without crashing or restarting. This issue occurs when an alias loop exists in the LDAP database. If an ldapsearch request is executed with alias dereferencing set to "always" on this alias entry, the server stops responding to all future requests. Fortunately, the server can be restarted without data corruption. This vulnerability is fixed in 4.9.3.

Las versiones anteriores a la 4.9.3 de OpenDJ contienen una vulnerabilidad de denegaci\u00f3n de servicio (DoS) que hace que el servidor deje de responder a todas las solicitudes LDAP sin bloquearse ni reiniciarse. Este problema se produce cuando existe un bucle de alias en la base de datos LDAP. Si se ejecuta una solicitud ldapsearch con la desreferenciaci\u00f3n de alias configurada en \"siempre\" en esta entrada de alias, el servidor deja de responder a todas las solicitudes futuras. Afortunadamente, el servidor se puede reiniciar sin que se produzcan da\u00f1os en los datos. Esta vulnerabilidad se solucion\u00f3 en la versi\u00f3n 4.9.3."
