What is CVE-2018-14635?

The vulnerability allows non-privileged tenants using the Linux bridge ml2 driver in OpenStack Neutron to create and attach network ports without specifying an IP address. This can lead to malicious users potentially assigning an IP address that conflicts with existing resources, resulting in a denial of service. Affected versions are those prior to 13.0.0.0b2, 12.0.3, and 11.0.5, which require immediate attention and remediation to ensure network integrity.

Affected Version(s)

openstack-neutron 13.0.0.0b2, 12.0.3, 11.0.5
