Descriptions

A flaw was found in the way qemu v1.3.0 and later (virtio-rng) validates addresses when guest accesses the config space of a virtio device. If the virtio device has zero/small sized config space, such as virtio-rng, a privileged guest user could use this flaw to access the matching host's qemu address space and thus increase their privileges on the host.

Se encontró un fallo en la manera en que qemu versión v1.3.0 y posteriores (virtio-rng) comprueba las direcciones cuando el invitado accede al espacio de configuración de un dispositivo virtio. Si el dispositivo virtio posee un espacio de configuración de tamaño cero o pequeño, ta y como virtio-rng, un usuario invitado privilegiado podría usar este fallo para acceder al espacio de direcciones qemu del host correspondiente y así aumentar sus privilegios en el host.
