{"id":"UBUNTU-CVE-2018-14635","details":"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.","modified":"2025-10-24T04:47:10Z","published":"2018-09-10T19:29:00Z","upstream":["CVE-2018-14635"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2018-14635"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2018-14635"}],"affected":[{"package":{"name":"neutron","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/neutron@2:8.4.0-0ubuntu7.5?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2:7.0.0-0ubuntu1","2:8.0.0~b1-0ubuntu2","2:8.0.0~b2-0ubuntu4","2:8.0.0~b2-0ubuntu5","2:8.0.0~b2-0ubuntu7","2:8.0.0~b3-0ubuntu1","2:8.0.0~rc1-0ubuntu1","2:8.0.0-0ubuntu1","2:8.1.0-0ubuntu0.16.04.2","2:8.1.2-0ubuntu1","2:8.2.0-0ubuntu1","2:8.3.0-0ubuntu1","2:8.3.0-0ubuntu1.1","2:8.3.0-0ubuntu1.2","2:8.4.0-0ubuntu1","2:8.4.0-0ubuntu2","2:8.4.0-0ubuntu3","2:8.4.0-0ubuntu4","2:8.4.0-0ubuntu5","2:8.4.0-0ubuntu6","2:8.4.0-0ubuntu7.1","2:8.4.0-0ubuntu7.2","2:8.4.0-0ubuntu7.3","2:8.4.0-0ubuntu7.4","2:8.4.0-0ubuntu7.5"],"ecosystem_specific":{"binaries":[{"binary_name":"neutron-bgp-dragent","binary_version":"2:8.4.0-0ubuntu7.5"},{"binary_name":"neutron-common","binary_version":"2:8.4.0-0ubuntu7.5"},{"binary_name":"neutron-dhcp-agent","binary_version":"2:8.4.0-0ubuntu7.5"},{"binary_name":"neutron-l3-agent","binary_version":"2:8.4.0-0ubuntu7.5"},{"binary_version":"2:8.4.0-0ubuntu7.5","binary_name":"neutron-linuxbridge-agent"},{"binary_name":"neutron-macvtap-agent","binary_version":"2:8.4.0-0ubuntu7.5"},{"binary_name":"neutron-metadata-agent","binary_version":"2:8.4.0-0ubuntu7.5"},{"binary_name":"neutron-metering-agent","binary_version":"2:8.4.0-0ubuntu7.5"},{"binary_name":"neutron-openvswitch-agent","binary_version":"2:8.4.0-0ubuntu7.5"},{"binary_name":"neutron-plugin-linuxbridge-agent","binary_version":"2:8.4.0-0ubuntu7.5"},{"binary_name":"neutron-plugin-ml2","binary_version":"2:8.4.0-0ubuntu7.5"},{"binary_name":"neutron-plugin-openvswitch-agent","binary_version":"2:8.4.0-0ubuntu7.5"},{"binary_name":"neutron-plugin-sriov-agent","binary_version":"2:8.4.0-0ubuntu7.5"},{"binary_version":"2:8.4.0-0ubuntu7.5","binary_name":"neutron-server"},{"binary_name":"neutron-sriov-agent","binary_version":"2:8.4.0-0ubuntu7.5"},{"binary_name":"python-neutron","binary_version":"2:8.4.0-0ubuntu7.5"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2018/UBUNTU-CVE-2018-14635.json"}},{"package":{"name":"neutron","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/neutron@2:12.0.3-0ubuntu1?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2:12.0.3-0ubuntu1"}]}],"versions":["2:11.0.1-0ubuntu1","2:12.0.0~b1-0ubuntu1","2:12.0.0~b1-0ubuntu2","2:12.0.0~b2-0ubuntu1","2:12.0.0~b3-0ubuntu1","2:12.0.0~rc1-0ubuntu1","2:12.0.0~rc2-0ubuntu1","2:12.0.0-0ubuntu1","2:12.0.0-0ubuntu1.1","2:12.0.0-0ubuntu1.2","2:12.0.0-0ubuntu1.3","2:12.0.0-0ubuntu1.4","2:12.0.0-0ubuntu2","2:12.0.0-0ubuntu3","2:12.0.1-0ubuntu1","2:12.0.1-0ubuntu1.1","2:12.0.2-0ubuntu1"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"neutron-common","binary_version":"2:12.0.3-0ubuntu1"},{"binary_name":"neutron-dhcp-agent","binary_version":"2:12.0.3-0ubuntu1"},{"binary_name":"neutron-l3-agent","binary_version":"2:12.0.3-0ubuntu1"},{"binary_name":"neutron-linuxbridge-agent","binary_version":"2:12.0.3-0ubuntu1"},{"binary_name":"neutron-macvtap-agent","binary_version":"2:12.0.3-0ubuntu1"},{"binary_name":"neutron-metadata-agent","binary_version":"2:12.0.3-0ubuntu1"},{"binary_name":"neutron-metering-agent","binary_version":"2:12.0.3-0ubuntu1"},{"binary_name":"neutron-openvswitch-agent","binary_version":"2:12.0.3-0ubuntu1"},{"binary_version":"2:12.0.3-0ubuntu1","binary_name":"neutron-plugin-linuxbridge-agent"},{"binary_version":"2:12.0.3-0ubuntu1","binary_name":"neutron-plugin-ml2"},{"binary_version":"2:12.0.3-0ubuntu1","binary_name":"neutron-plugin-openvswitch-agent"},{"binary_name":"neutron-plugin-sriov-agent","binary_version":"2:12.0.3-0ubuntu1"},{"binary_name":"neutron-server","binary_version":"2:12.0.3-0ubuntu1"},{"binary_name":"neutron-sriov-agent","binary_version":"2:12.0.3-0ubuntu1"},{"binary_name":"python-neutron","binary_version":"2:12.0.3-0ubuntu1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2018/UBUNTU-CVE-2018-14635.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"},{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"},{"type":"Ubuntu","score":"negligible"}]}
