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.","published":"2018-09-10T19:29:00.313Z","modified":"2026-10-24T10:49:37.440235356Z","cvss":{"score":6.5,"severity":"MEDIUM","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"},"epss":{"score":0.02527,"percentile":0.83586,"asOf":"2026-08-23"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"neutron","fixedVersion":"13.0.0.0b2"},{"ecosystem":"PyPI","name":"neutron","fixedVersion":"11.0.6"},{"ecosystem":"PyPI","name":"neutron","fixedVersion":"12.0.4"}],"fix":{"url":"https://github.com/openstack/neutron/commit/54aa6e81cb17b33ce4d5d469cc11dec2869c762d","label":"openstack/neutron@54aa6e8"},"references":[{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2018:2710"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2018:2715"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2018:2721"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2018:3792"},{"type":"ADVISORY","url":"https://bugs.launchpad.net/neutron/+bug/1757482"},{"type":"FIX","url":"https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-14635"},{"type":"FIX","url":"https://git.openstack.org/cgit/openstack/neutron/commit/?id=54aa6e81cb17b33ce4d5d469cc11dec2869c762d"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2018-14635"},{"type":"WEB","url":"https://github.com/openstack/neutron/commit/54aa6e81cb17b33ce4d5d469cc11dec2869c762d"},{"type":"PACKAGE","url":"https://github.com/openstack/neutron"},{"type":"WEB","url":"https://github.com/pypa/advisory-database/tree/main/vulns/neutron/PYSEC-2018-93.yaml"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-24T10:49:37.440235356Z"}}
