Descriptions

The do_change_type function in fs/namespace.c in the Linux kernel before 2.6.22 does not verify that the caller has the CAP_SYS_ADMIN capability, which allows local users to gain privileges or cause a denial of service by modifying the properties of a mountpoint.

La función do_change_type en fs/namespace.c del núcleo de Linux en versiones anteriores a 2.6.22 no verifica que la persona que llama tiene la capacidad CAP_SYS_ADMIN, lo cual permite a usuarios locales conseguir privilegios o provocar una denegación de servicio mediante la modificación de las propiedades de un punto de montaje.
