RHSA-2014:1078 - Security Advisory

Topic

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.

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.
