CVE-2009-3556

Estado: ModificadaBaja (1.9)—

Un paso en la configuración para el controlador qla2xxx sobre el Kernel 2.6.18 en Red Hat Enterprise Linux (RHEL) 5, cuando se usa el hardware N_Port ID Virtualization (NPIV), establece los permisos de escritura para "todo el mundo" (world_writable) sobre los archivos (1) vport_create y (2) vport_delete bajo el directorio /sys/class/scsi_host/, lo que permite a usuarios locales , mediante la modificación de estos archivos, realizar cambios de su elección a los atributos en el host SCSI.
