Descriptions
net/netfilter/xt_osf.c in the Linux kernel through 4.14.4 does not require the CAP_NET_ADMIN capability for add_callback and remove_callback operations, which allows local users to bypass intended access restrictions because the xt_osf_fingers data structure is shared across all net namespaces.
net/netfilter/xt_osf.c en el kernel de Linux hasta la versiĆ³n 4.14.4 no requiere la capacidad CAP_NET_ADMIN para operaciones "add_callback" y "remove_callback", lo que permite que usuarios locales omitan las restricciones de acceso establecidas debido a que la estructura de datos xt_osf_fingers se comparte entre todos los espacios de nombres de la red.
