-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 =========================================================================================== 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.
