Type/Severity
Security Advisory: Moderate
Red Hat Insights patch analysis
Identify and remediate systems affected by this advisory.
Topic
Updated openstack-neutron packages that fix one security issue and one bug
are now available for Red Hat Enterprise Linux OpenStack Platform 5.0 for
Red Hat Enterprise Linux 6.
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. As of Red
Hat Enterprise Linux OpenStack Platform 4.0, 'neutron' replaces 'quantum'
as the core component of OpenStack Networking.
A denial of service flaw was found in the way neutron handled the
'dns_nameservers' parameter. By providing specially crafted
'dns_nameservers' values, an authenticated user could use this flaw to
crash the neutron service. (CVE-2014-7821)
Red Hat would like to thank the OpenStack project for reporting this issue.
Upstream acknowledges Henry Yamauchi, Charles Neill, and Michael Xin
(Rackspace) as the original reporters.
This update also fixes the following bug:
- The "/var/log/neutron/" directory was world-readable. With this update,
world-read permissions have been removed. (BZ#1149688)
All openstack-neutron users are advised to upgrade to these updated
packages, which contain backported patches to correct these issues.
Solution
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
