Subject: [OSSA 2013-033] Metadata queries from Neutron to Nova are not
 restricted by tenant (CVE-2013-6419)

OpenStack Security Advisory: 2013-033
CVE: CVE-2013-6419
Date: December 11, 2013
Title: Metadata queries from Neutron to Nova are not restricted by tenant
Reporter: Aaron Rosen (VMware)
Products: Neutron, Nova
Affects: All supported releases

Aaron Rosen from VMware reported a vulnerability in the metadata
access from OpenStack Neutron to Nova. Because of a missing
authorization check on port binding, by guessing an instance_id a
tenant may retrieve another tenant's metadata resulting in
information disclosure. Only OpenStack setups running
neutron-metadata-agent are affected.

Icehouse (development branch) fix: (neutron) (nova)

Havana fix: (neutron) (nova)

Grizzly fix: (neutron) (nova)

This fix will be included in the icehouse-2 development milestone
and in a future 2013.2.1 release.
