Descriptions
The pivot_root implementation in fs/namespace.c in the Linux kernel through 3.17 does not properly interact with certain locations of a chroot directory, which allows local users to cause a denial of service (mount-tree loop) via . (dot) values in both arguments to the pivot_root system call.
La implementación pivot_root en fs/namespace.c en el kernel de Linux hasta 3.17 no interactúa debidamente con ciertas localizaciones de un directorio chroot, lo que permite a usuarios locales causar una denegación de servicio (bucle de montaje de árbol) a través de valores . (punto) en ambos argumentos en la llamada de sistema pivot_root.
