An improper authorization flaw was discovered in openstack-selinux's applied policy where it does not prevent a non-root user in a container from privilege escalation. A non-root attacker in one or more Red Hat OpenStack (RHOSP) containers could send messages to the dbus. With access to the dbus, the attacker could start or stop services, possibly causing a denial of service. Versions before openstack-selinux 0.8.24 are affected.

CVE-2020-1690 openstack-selinux: policy flaw allows dbus messaging
As of 15, openstack-selinux prevents a non-root user in a container from privilege escalation. In 13 and before, openstack-selinux didn't have this functionality (that is, selinux separation wasn't possible).
Updates to the policy in [1] broke 15's functionality. A non-root user in one or more RHOSP containers can send messages to the dbus. With access to the dbus, services could be started or stopped, therefore a DoS is possible.
