-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: openstack-nova security update Advisory ID: RHSA-2016:0018-01 Product: Red Hat Enterprise Linux OpenStack Platform Advisory URL: https://rhn.redhat.com/errata/RHSA-2016-0018.html Issue date: 2016-01-11 CVE Names: CVE-2015-7548 ===================================================================== 1. Summary: Updated openstack-nova packages that fix one security issue are now available for Red Hat Enterprise Linux OpenStack Platform 5.0, 6.0, and 7.0 for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having Important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux OpenStack Platform 5.0 for RHEL 7 - noarch Red Hat Enterprise Linux OpenStack Platform 6.0 for RHEL 7 - noarch Red Hat Enterprise Linux OpenStack Platform 7.0 for RHEL 7 - noarch 3. Description: 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. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. For details on how to apply this update, refer to: https://access.redhat.com/articles/11258 5.
