Description Jason Shepherd 2018-07-01 23:39:12 EDT

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 2018-07-01 23:41:19 EDT

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
