RedHat: RHSA-2016-0018:01 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.
A flaw was discovered in the OpenStack Compute (nova) snapshot feature when
using the libvirt driver. A compute user could overwrite an attached
instance disk with a malicious header specifying a backing file, and then
request a snapshot, causing a file from the compute host to be leaked. This
flaw only affects LVM or Ceph setups, or setups using filesystem storage
with "use_cow_images = False". (CVE-2015-7548)
This issue was discovered by Matthew Booth of Red Hat OpenStack
Engineering.
All openstack-nova users are advised to upgrade to these updated packages,
which correct this issue.
