CVE-2015-3241

Status Candidate

Overview

OpenStack Compute (nova) 2015.1 through 2015.1.1, 2014.2.3, and earlier does not stop the migration process when the instance is deleted, which allows remote authenticated users to cause a denial of service (disk, network, and other resource consumption) by resizing and then deleting an instance.

Red Hat Security Advisory 2015-1898-01 - 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. A denial of service flaw was found in the OpenStack Compute instance migration process. Because the migration process does not terminate when an instance is deleted, an authenticated user could bypass user quota and deplete all available disk space by repeatedly re-sizing and deleting an instance.
