OSSA-2019-002: Overlapping security group rules prevents compute node
network configuration
===========================================================================================
:Date: April 08, 2019
:CVE: CVE-2019-10876
Affects
~~~~~~~
- - Neutron: >=11.0.0 <11.0.7, >=12.0.0 <12.0.6, >=13.0.0 <13.0.3
Description
~~~~~~~~~~~
Diko Parvanov (Canonical) reported a vulnerability in neutron-
openvswitch-agent security group rules. By creating two security
groups with separate/overlapping port ranges, an authenticated user
may prevent neutron from being able to configure networks on any
compute nodes where those security groups are present. All neutron
deployments utilizing neutron-openvswitch-agent are affected.
