RedHat: RHSA-2016-0364:01 Important: openstack-nova security update
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.
