Description Jason Shepherd 2018-07-02 03:39:12 UTC 
A malicious network-policy configuration can cause Openshift Routing to crash when using ovs-network policy plugin. An attacker can use this flaw to cause a Denial of Service (DoS) attack on an Openshift 3.9 Cluster.
Comment 2 Jason Shepherd 2018-07-02 03:41:19 UTC 
The ovs-networkpolicy plugin was tech preview until the 3.7 release, ref: https://docs.openshift.com/container-platform/3.6/install_config/configuring_sdn.html

Mitigation:

Use an alternative plugin such as ovs-subnet, or ovs-multitentant if delivering a multitentant service.
