Descriptions
The create_user_ns function in kernel/user_namespace.c in the Linux kernel before 3.8.6 does not check whether a chroot directory exists that differs from the namespace root directory, which allows local users to bypass intended filesystem restrictions via a crafted clone system call.
La función create_user_ns en kernel/user_namespace.c en el kernel Linux antes de v3.8.6 no comprueba si existe un directorio de chroot que difiere del directorio raíz de espacio de nombres, que permite a los usuarios locales para eludir las restricciones del sistema de archivos destinados a través de una llamada al sistema clone diseñado.
