Descriptions
Xen through 4.14.x allows guest OS administrators to obtain sensitive information (such as AES keys from outside the guest) via a side-channel attack on a power/energy monitoring interface, aka a "Platypus" attack. NOTE: there is only one logically independent fix: to change the access control for each such interface in Xen.
Xen versiones hasta 4.14.x, permite a administradores de Sistemas Operativos invitados obtener información confidencial (tales como claves AES desde fuera del invitado) por medio de un ataque de canal lateral en una interfaz de monitoreo de power/energy, también se conoce como un ataque "Platypus". NOTA: solo existe una corrección lógicamente independiente: cambiar el control de acceso para cada interfaz de este tipo en Xen
