=====================================================================

 

1. Summary:

 

Updated openstack-neutron packages that fix one security issue are now

available for Red Hat Enterprise Linux OpenStack Platform 4.0.

 

Red Hat Product Security has rated this update as having Moderate security

impact. A Common Vulnerability Scoring System (CVSS) base score, which

gives a detailed severity rating, is available from the CVE link in the

References section.

 

2. Relevant releases/architectures:

 

Red Hat Enterprise Linux OpenStack Platform 4.0 - noarch

 

3. Description:

 

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 denial of service flaw was found in Neutron's handling of allowed address

pairs. There was no enforced quota on the amount of allowed address pairs,

possibly allowing a sufficiently authorized user to create such a large

number of firewall rules as to impact performance, or potentially render a

compute node unusable. (CVE-2014-3555)

 

Red Hat would like to thank the OpenStack project for reporting this issue.

Upstream acknowledges Liping Mao from Cisco as the original reporter.

 

All openstack-neutron users are advised to upgrade to these updated

packages, which correct this issue.
