Dist Redhat Esm H88
A vital patch for Red Hat OpenStack Platform 8 fixes vulnerabilities in memcached that may lead to Denial of Service attacks, ensuring stability and reliability

Solution

For details on how to apply this update, which includes the changes described in this advisory, refer to:

https://access.redhat.com/articles/11258

Summary

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)
