Summary

OpenStack Compute (nova) 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.
An information-exposure flaw was found in the OpenStack Compute (nova) resize and migrate functionality. An authenticated user could write a malicious qcow header to an ephemeral or root disk, referencing a block device as a backing file. With a subsequent resize or migration, file system content on the specified device would be leaked to the user. Only setups using libvirt with raw storage and "use_cow_images = False" were affected. (CVE-2016-2140)
This issue was discovered by Matthew Booth of Red Hat.
All openstack-nova users are advised to upgrade to these updated packages, which correct this issue.
