1. Summary:

 

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

2. Relevant releases/architectures:

 

Red Hat Enterprise Linux OpenStack Platform 5.0 for RHEL 6 - 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)

 

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.
