Summary
Red Hat Security Advisory: openstack-nova security advisory

Notes

Topic
Updated openstack-nova packages that fix two security issues are now available for Red Hat Enterprise Linux OpenStack Platform 5.0 for Red Hat Enterprise Linux 6. Red Hat Product Security has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.
Details
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) A vulnerability was discovered in the way OpenStack Compute (nova) networking handled security group updates; changes were not applied to already running VM instances. A remote attacker could use this flaw to access running VM instances. (CVE-2015-7713) The CVE-2015-7548 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 these issues.
