The following packages have been upgraded to a later upstream version: vdsm (4.20.47). (BZ#1677458)
Security Fix(es):
* vdsm: privilege escalation to root via systemd_run (CVE-2019-3831)
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.
Bug Fix(es):
* 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 related information are not recorded in the system log. As a result, the system log is quieter. (BZ#1673765)
