+title: Unsupported dport option prevents applying security groups
+
+description: >
+  Erik Olof Gunnar Andersson with Blizzard Entertainment reported a
+  vulnerability in Neutron's iptables firewall module. By setting a
+  destination port in a security group rule along with a protocol
+  which doesn't support that option (for example, VRRP), an
+  authenticated user may block further application of security group
+  rules for instances from any project/tenant on the compute hosts
+  to which it's applied. Only deployments using the iptables
+  security group driver are affected.
