{"id":"CVE-2019-9735","details":"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.)","aliases":["GHSA-9773-3fqg-8w25","PYSEC-2019-190"],"modified":"2026-07-08T05:55:12.004451230Z","published":"2019-03-13T02:29:00.277Z","related":["SUSE-SU-2019:2219-1","SUSE-SU-2019:2267-1"],"database_specific":{"unresolved_ranges":[{"source":"CPE_RANGE","vendor_product":"openstack:neutron","cpes":["cpe:2.3:a:openstack:neutron:*:*:*:*:*:*:*:*"],"extracted_events":[{"fixed":"10.0.8"}]},{"cpes":["cpe:2.3:o:debian:debian_linux:9.0:*:*:*:*:*:*:*"],"extracted_events":[{"introduced":"9.0"},{"last_affected":"9.0"}],"source":"CPE_STRING","vendor_product":"debian:debian_linux"},{"vendor_product":"redhat:openstack","cpes":["cpe:2.3:a:redhat:openstack:10:*:*:*:*:*:*:*","cpe:2.3:a:redhat:openstack:13:*:*:*:*:*:*:*","cpe:2.3:a:redhat:openstack:14:*:*:*:*:*:*:*"],"extracted_events":[{"introduced":"10"},{"last_affected":"10"},{"introduced":"13"},{"last_affected":"13"},{"introduced":"14"},{"last_affected":"14"}],"source":"CPE_STRING"}]},"references":[{"type":"WEB","url":"https://usn.ubuntu.com/4036-1/"},{"type":"ADVISORY","url":"http://www.openwall.com/lists/oss-security/2019/03/18/2"},{"type":"ADVISORY","url":"http://www.securityfocus.com/bid/107390"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:0879"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:0916"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:0935"},{"type":"ADVISORY","url":"https://seclists.org/bugtraq/2019/Mar/24"},{"type":"ADVISORY","url":"https://www.debian.org/security/2019/dsa-4409"},{"type":"FIX","url":"https://launchpad.net/bugs/1818385"},{"type":"FIX","url":"https://security.openstack.org/ossa/OSSA-2019-001.html"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/openstack/neutron","events":[{"introduced":"5212c9c563e9470ce9e6abd76bdef22fa652a9b3"},{"fixed":"7ba0d8fb49ad2f86683172ed6fc06fdb44b473a6"},{"introduced":"fb3f71806174bc2fae7e421268aeee61be36412d"},{"fixed":"871b86390a024f19876cda06f2775d6785400878"},{"introduced":"b6314ea6c3df11c6b27cd39844c53b65be0d9060"},{"fixed":"31a48bea869f3b7fafcf8ec2fae683456885c3cf"}],"database_specific":{"cpe":"cpe:2.3:a:openstack:neutron:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"11.0.0"},{"fixed":"11.0.7"},{"introduced":"12.0.0"},{"fixed":"12.0.6"},{"introduced":"13.0.0"},{"fixed":"13.0.3"}],"source":"CPE_RANGE"}}],"versions":["13.0.2","11.0.6","12.0.5","13.0.1","12.0.4","13.0.0.0rc2","13.0.0","12.0.3","11.0.5","11.0.4","12.0.2","12.0.1","11.0.3","12.0.0.0rc2","12.0.0","11.0.2","11.0.1","11.0.0.0rc3","11.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2019-9735.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
