| CVE-2019-9735 | 3 Debian, Openstack, Redhat | 3 Debian Linux, Neutron, Openstack | 2023-12-10 | 4.0 MEDIUM | 6.5 MEDIUM |
| An issue was discovered in the iptables firewall module in OpenStack Neutron before 10.0.8, 11.x before 11.0.7, 12.x before 12.0.6, and 13.x before 13.0.3. By setting a destination port in a security group rule along with a protocol that 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.) | |||||
| CVE-2019-10876 | 2 Openstack, Redhat | 2 Neutron, Openstack | 2023-12-10 | 4.0 MEDIUM | 6.5 MEDIUM |
| An issue was discovered in OpenStack Neutron 11.x before 11.0.7, 12.x before 12.0.6, and 13.x before 13.0.3. 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, because of an Open vSwitch (OVS) firewall KeyError. All Neutron deployments utilizing neutron-openvswitch-agent are affected. | |||||
| CVE-2017-7543 | 2 Openstack, Redhat | 3 Neutron, Enterprise Linux, Openstack | 2023-12-10 | 4.3 MEDIUM | 5.9 MEDIUM |
| A race-condition flaw was discovered in openstack-neutron before 7.2.0-12.1, 8.x before 8.3.0-11.1, 9.x before 9.3.1-2.1, and 10.x before 10.0.2-1.1, where, following a minor overcloud update, neutron security groups were disabled. Specifically, the following were reset to 0: net.bridge.bridge-nf-call-ip6tables and net.bridge.bridge-nf-call-iptables. The race was only triggered by an update, at which point an attacker could access exposed tenant VMs and network resources. | |||||
| CVE-2018-14636 | 1 Openstack | 1 Neutron | 2023-12-10 | 3.5 LOW | 5.3 MEDIUM |
| Live-migrated instances are briefly able to inspect traffic for other instances on the same hypervisor. This brief window could be extended indefinitely if the instance's port is set administratively down prior to live-migration and kept down after the migration is complete. This is possible due to the Open vSwitch integration bridge being connected to the instance during migration. When connected to the integration bridge, all traffic for instances using the same Open vSwitch instance would potentially be visible to the migrated guest, as the required Open vSwitch VLAN filters are only applied post-migration. Versions of openstack-neutron before 13.0.0.0b2, 12.0.3, 11.0.5 are vulnerable. | |||||
| CVE-2018-14635 | 2 Openstack, Redhat | 2 Neutron, Openstack | 2023-12-10 | 4.0 MEDIUM | 6.5 MEDIUM |
| When using the Linux bridge ml2 driver, non-privileged tenants are able to create and attach ports without specifying an IP address, bypassing IP address validation. A potential denial of service could occur if an IP address, conflicting with existing guests or routers, is then assigned from outside of the allowed allocation pool. Versions of openstack-neutron before 13.0.0.0b2, 12.0.3 and 11.0.5 are vulnerable. | |||||
