Descriptions

It was found that the "mknod" call derived from mknod(2) can create files pointing to devices on a glusterfs server node. An authenticated attacker could use this to create an arbitrary device and read data from any device attached to the glusterfs server node.

Se ha detectado que la llamada "mknod" derivada de mknod(2) puede crear archivos que señalan a dispositivos en un nodo del servidor glusterfs. Un atacante autenticado podría emplearlo para crear un dispositivo arbitrario y leer datos desde cualquier dispositivo conectado al nodo del servidor glusterfs.
