Descriptions

Multiple memory leaks in Xen 4.0 through 4.6.x allow local guest administrators or domains with certain permission to cause a denial of service (memory consumption) via a large number of "teardowns" of domains with the vcpu pointer array allocated using the (1) XEN_DOMCTL_max_vcpus hypercall or the xenoprofile state vcpu pointer array allocated using the (2) XENOPROF_get_buffer or (3) XENOPROF_set_passive hypercall.

Fugas de memoria múltiples en Xen 4.0 hasta la versión 4.6.x permite a administradores locales invitados o dominios con cierto permiso provocar una denegación de servicio (consumo de memoria) a través de un gran número de 'desensamblajes' de dominios con el array de punteros vcpu asignados utilizando (1) la hypercall XEN_DOMCTL_max_vcpus o el array de punteros vcpu asignados en el estado xenoprofile utilizando la hypercall (2) XENOPROF_get_buffer o (3) XENOPROF_set_passive .
