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
* memcached: UDP server support allows spoofed traffic amplification DoS
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.
* 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
* Prior to this update, the source IP address for cold migration and resize
was determined by the default gateway configured on the source compute
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.
