Descriptions

The i_create_images_and_backing (aka create_images_and_backing) method in libvirt driver in OpenStack Compute (Nova) Grizzly, Havana, and Icehouse, when using KVM live block migration, does not properly create all expected files, which allows attackers to obtain snapshot root disk contents of other users via ephemeral storage.

El método i_create_images_and_backing (también conocido como create_images_and_backing) en el driver libvirt en OpenStack Compute (Nova) Grizzly, Havana, and Icehouse, cuando hace uso de un bloque de migración KVM en vivo, no crea debidamente todos los archivos esperados, lo que permite a atacantes obtener contenido de una instantánea del disco raíz de otros usuarios a través del almacenamiento efímero.

OpenStack Compute launches and schedules large networks of virtual machines, creating a redundant and scalable cloud computing platform. Compute provides the software, control panels, and APIs required to orchestrate a cloud, including running virtual machine instances, managing networks, and controlling access through users and projects. It was discovered that the metadata agent in OpenStack Networking was missing an authorization check on the device ID that is bound to a specific port. A remote tenant could guess the instance ID bound to a port and retrieve metadata of another tenant, resulting in information disclosure. Note that only OpenStack Networking setups running neutron-metadata-agent were affected.
