Linux Bridge ML2 Driver IP Address Bypass Vulnerability

CVE-2018-14635 · MEDIUM Severity

AV:N/AC:L/AU:S/C:N/I:N/A:P

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.
