-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 =========================================================================== AUSCERT External Security Bulletin Redistribution ESB-2014.2272 Moderate: openstack-neutron security and bug fix update 3 December 2014 =========================================================================== AusCERT Security Bulletin Summary --------------------------------- Product: openstack-neutron Publisher: Red Hat Operating System: Linux variants Solaris Red Hat Enterprise Linux Server 6 Red Hat Enterprise Linux Server 7 Impact/Access: Denial of Service -- Existing Account Resolution: Patch/Upgrade CVE Names: CVE-2014-7821 Original Bulletin: https://rhn.redhat.com/errata/RHSA-2014-1938.html https://rhn.redhat.com/errata/RHSA-2014-1942.html Comment: This advisory references vulnerabilities in products which run on platforms other than Red Hat. It is recommended that administrators running openstack-neutron check for an updated version of the software for their operating system. This bulletin contains two (2) Red Hat security advisories. - --------------------------BEGIN INCLUDED TEXT-------------------- - -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: openstack-neutron security and bug fix update 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 CVE Names: CVE-2014-7821 ===================================================================== 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. 1163457 - CVE-2014-7821 openstack-neutron: DoS via maliciously crafted dns_nameservers 6.

This update also fixes the following bugs: * Prior to this update, the network name and UUID were not sent to N1KV during the subnet creation process. Consequently, N1KV was unable to properly associate the network and subnet in its local configuration. This update addresses this issue by sending the required network name and UUID during subnet creation, with the result that they are now properly associated on the N1KV. (BZ#1118508) * Previously, a rollback did not result in all entries being cleared from the N1KV-specific database tables, resulting in the presence of stale entries. This update addresses the issue by performing a proper cleanup of all N1KV tables. Consequently, stale entries are no longer left in the N1KV tables. (BZ#1124991) * Previously, the N1KV OpenStack Networking (neutron) plug-in did not sent the subtype for overlay networks during the network segment pool creation process. This update addresses this issue by sending the required details during the creation process. (BZ#1130336) All openstack-neutron users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. 4.
