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

* VDSM attempted to collect OpenStack related information, even on hosts
that are not connected to OpenStack, and displayed a repeated error message
in the system log. In this release, errors originating from OpenStack

system log is quieter. (BZ#1673765)
