title: 'Neutron security groups bypass through invalid CIDR'
description: 'Stephen Ma from Hewlett Packard and Christoph Thiel from Deutsche Telekom
reported a vulnerability in Neutron security groups. By creating a security group
rule with an invalid CIDR, an authenticated user may break openvswitch-agent process,
preventing further rules from being applied on the host. Note: removal of the faulty
rule is not enough, the openvswitch-agent must be restarted. All Neutron setups
using Open vSwitch are affected.'
