    Advisory ID:       RHSA-2014:1938-01
    Product:           Red Hat Enterprise Linux OpenStack Platform
    Advisory URL:      https://rhn.redhat.com/errata/RHSA-2014-1938.html
    Issue date:        2014-12-02

    =====================================================================
    
    1. Summary:
    
    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.
    
    2. Relevant releases/architectures:
    
    Red Hat Enterprise Linux OpenStack Platform 5.0 for RHEL 6 - 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. 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.
    
    4. Solution:
    
    Before applying this update, make sure all previously released errata
    relevant to your system have been applied.
    
    This update is available via the Red Hat Network. Details on how to use the
    Red Hat Network to apply this update are available at
    https://access.redhat.com/articles/11258
    
    5. Bugs fixed (https://bugzilla.redhat.com/):
    
    1149688 - /var/log/neutron/ and all logs within it are world readable.
