Descriptions

The overlayfs implementation in the linux (aka Linux kernel) package before 3.19.0-21.21 in Ubuntu through 15.04 does not properly check permissions for file creation in the upper filesystem directory, which allows local users to obtain root access by leveraging a configuration in which overlayfs is permitted in an arbitrary mount namespace.

La implementación de overlayfs en el paquete linux (también conocido como kernel Linux) en versiones anteriores a 3.19.0-21.21 en Ubuntu hasta la versión 15.04 no comprueba adecuadamente permisos para la creación de archivos en el directorio de sistema de archivos upper, lo que permite a usuarios locales obtener acceso de root aprovechando una configuración donde overlayfs es permitido en un espacio de nombre de montaje arbitrario.
