RHSA-2018:2857 - Moderate: Red Hat OpenStack Platform 8 director security and bug fix update

Synopsis

Moderate: Red Hat OpenStack Platform 8 director security and bug fix update

Type/Severity

Security Advisory Moderate

Topic

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.

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)
