Descriptions

The capabilities implementation in the Linux kernel before 3.14.8 does not properly consider that namespaces are inapplicable to inodes, which allows local users to bypass intended chmod restrictions by first creating a user namespace, as demonstrated by setting the setgid bit on a file with group ownership of root.

La implementación de capacidades en el kernel de Linux anterior a 3.14.8 no considera debidamente que los espacios de nombres no sean aplicables a inodos, lo que permite a usuarios locales evadir restricciones chmod mediante la creación anterior de un espacio de nombre de usuario, tal y como fue demostrado mediante la configuración del bit setgid en un fichero con propiedad de grupo del root.
