Issue date: 2018-10-02

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

1. Summary:

An update for instack-undercloud and openstack-tripleo-heat-templates is
now available for Red Hat OpenStack Platform 8.0 (Liberty) director.

Red Hat Product Security has rated this update as having a security impact
of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available for each vulnerability from
the CVE link(s) in the References section.

2. Relevant releases/architectures:

OpenStack 8.0 Director for RHEL 7 - noarch

3. Description:

memcached is a high-performance, distributed memory object caching system,
generic in nature, but intended for use in speeding up dynamic web
applications by alleviating database load.

instack-undercloud provides a collection of scripts and elements that can
be used to install an OpenStack undercloud (using python-instack).

openstack-tripleo-heat-templates is a collection of OpenStack Orchestration
templates and tools (codename heat), which can be used to help deploy
OpenStack.

Security Fix(es):

* memcached: UDP server support allows spoofed traffic amplification DoS
(CVE-2018-1000115)

For more details about the security issue(s), including the impact, a CVSS
score, and other related information, refer to the CVE page(s) listed in
the References section.

Bug Fix(es):

* This update fixes a race condition that could cause pacemaker-managed
glance-fs deployments to fail.

Now the glance-fs resource is created from a single node of the overcloud
in a way that eliminates the race condition and the resultant deployment
failures. (BZ#1418617)

* Prior to this update, the source IP address for cold migration and resize
was determined by the default gateway configured on the source compute
node.

Now the my_ip option is explicitly set to the internal_api network IP in
nova.conf, ensuring the correct network is used for this traffic.
(BZ#1552855)
