Descriptions

The device file system (devfs) in FreeBSD 5.x does not properly check parameters of the node type when creating a device node, which makes hidden devices available to attackers, who can then bypass restrictions on a jailed process.

El sistema de ficheros de dispositivos en FreeBSD 5.x no comprueba adecuadamente los parámetros del tipo de nodo cuando crea un nodo de dispositivo, lo que hace que dispositivos ocultos estén disponibles a tacantes (quienes pueden por tanto sortear restricciones en ciertos procesos).

Due to insufficient parameter checking of the node type during device creation, any user can expose hidden device nodes on devfs mounted file systems within their jail. Device nodes will be created in the jail with their normal default access permissions.
