Descriptions

The NFS client implementation in the kernel in Red Hat Enterprise Linux (RHEL) 3, when a filesystem is mounted with the noacl option, checks permissions for the open system call via vfs_permission (mode bits) data rather than an NFS ACCESS call to the server, which allows local client processes to obtain a false success status from open calls that the server would deny, and possibly obtain sensitive information about file permissions on the server, as demonstrated in a root_squash environment. NOTE: it is uncertain whether any scenarios involving this issue cross privilege boundaries.

La implementación del cliente NFS en el núcleo de Red Hat Enterprise Linux (RHEL) 3, cuando un sistema de ficheros se monta con la opción noacl, comprueba los permisos para la llamada al sistema open mediante la información vfs_permission (bits de modo o mode bits) en lugar de una llamada NFS ACCESS al servidor, lo cual permite a procesos cliente locales obtener un falso estado de éxito de llamadas a open que el servidor denegaría, y posiblemente obtener información sensible sobre los permisos de fichero en el servidor, como se ha demostrado en un entorno root_squash. NOTA: no está claro si cualquier escenario involucrando este problema cruzan los límites de la seguridad.
