Descriptions

A certain Red Hat configuration step for the qla2xxx driver in the Linux kernel 2.6.18 on Red Hat Enterprise Linux (RHEL) 5, when N_Port ID Virtualization (NPIV) hardware is used, sets world-writable permissions for the (1) vport_create and (2) vport_delete files under /sys/class/scsi_host/, which allows local users to make arbitrary changes to SCSI host attributes by modifying these files.

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.
