Descriptions
In OpenStack Nova through 14.0.9, 15.x through 15.0.7, and 16.x through 16.0.2, by rebuilding an instance, an authenticated user may be able to circumvent the Filter Scheduler bypassing imposed filters (for example, the ImagePropertiesFilter or the IsolatedHostsFilter). All setups using Nova Filter Scheduler are affected. Because of the regression described in Launchpad Bug #1732947, the preferred fix is a 14.x version after 14.0.10, a 15.x version after 15.0.8, or a 16.x version after 16.0.3.
En OpenStack Nova hasta la versión 14.0.9, 15.x hasta la versión 15.0.7 y 16.x hasta la versión 16.0.2, al reconstrur una instancia, un usuario autenticado podría saltarse el Filter Scheduler omitiendos los filtros impuestos (por ejemplo, ImagePropertiesFilter o IsolatedHostsFilter). Todas las configuraciones que utilizan Nova Filter Scheduler se ven afectadas. Dada la regresión descrita en Launchpad Bug #1732947, la solución preferida es una versión 14.x posterior a la 14.0.10, una 15.x posterior a la 15.0.8 o una versión 16.x posterior a la 16.0.3.
By rebuilding an instance using a new image, an authenticated user may be able to circumvent the Filter Scheduler, bypassing imposed filters (for example, the ImagePropertiesFilter or the IsolatedHostsFilter).
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 and controlling access through users and projects. python-novaclient is the python client for the OpenStack Nova API. The client's Python API and command-line script both implement 100% of the OpenStack Nova API. The following packages have been upgraded to a later upstream version: openstack-nova, python-novaclient.
