CVE-2018-14635 (opens in a new tab)How to fix?
There is no fixed version for Debian:9 neutron.
NVD Description
Note: Versions mentioned in the description apply only to the upstream neutron package and not the neutron package as distributed by Debian.
See How to fix? for Debian:9 relevant fixed versions and status.
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.
