=====================================================================

1. Summary:

Updated openstack-packstack and openstack-puppet-modules packages that fix
one security issue and adds one enhancement are now available for Red Hat
Enterprise Linux OpenStack Platform 5.0 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

3. Description:

PackStack is a command-line utility for deploying OpenStack on existing
servers over an SSH connection. Deployment options are provided either
interactively, using the command line, or non-interactively by means of a
text file containing a set of preconfigured values for OpenStack
parameters. PackStack is suitable for deploying proof-of-concept
installations.

It was discovered that the puppet manifests, as provided with the
openstack-puppet-modules package, would configure the pcsd daemon with a
known default password. If this password was not changed and an attacker
was able to gain access to pcsd, they could potentially run shell
commands as root. (CVE-2015-1842)

This issue was discovered by Alessandro Vozza of Red Hat.

This update also adds the following enhancement:

* If OpenStack Networking (neutron) is enabled, Packstack now displays a
warning if the Network Manager service is active on hosts. (BZ#1117115)

All openstack-packstack and openstack-puppet-modules users are advised to
upgrade to these updated packages, which corrects this issue and adds
this enhancement.

4. Solution:

Before applying this update, ensure all previously released errata
relevant to your system have been applied.
