RHEL 6 / 7 : openstack-neutron (RHSA-2015:1909)

medium Nessus Plugin ID 193840

Synopsis

The remote Red Hat host is missing a security update for openstack-neutron.

Description

The remote Redhat Enterprise Linux 6 / 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2015:1909 advisory.

OpenStack Networking (neutron) is a pluggable, scalable, and API-driven system that provisions networking services to virtual machines. Its main function is to manage connectivity to and from virtual machines.

A race-condition flaw leading to ACL bypass was discovered in OpenStack Networking. An authenticated user could change the owner of a port after it was created but before firewall rules were applied, thus preventing firewall control checks from occurring. All OpenStack Networking deployments that used either the ML2 plug-in or a plug-in that relied on the security groups AMQP API were affected. (CVE-2015-5240)

Red Hat would like to thank the OpenStack project for reporting this issue.
Upstream acknowledges Kevin Benton from Mirantis as the original reporter.

All openstack-neutron users are advised to upgrade to these updated packages, which contain backported patches to correct these issues.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL openstack-neutron package based on the guidance in RHSA-2015:1909.
