Estado: ModificadaBaja (2.1)—

usr/log.c en iscsid en open-iscsi (iscsi-initiator-utils) anterior a 2.0-865 utiliza un semáforo con permisos no seguros (world-writable/world-readable) para gestionar los mensajes de log utilizando memoria compartida, lo cual permite a usuarios locales provocar denegación de servicio (cuelgue) tomando el semáforo.
