-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: openstack-nova security and bug fix advisory Advisory ID: RHSA-2015:2673-01 Product: Red Hat Enterprise Linux OpenStack Platform Advisory URL: https://access.redhat.com/errata/RHSA-2015:2673 Issue date: 2015-12-21 CVE Names: CVE-2015-7713 ===================================================================== 1. Summary: Updated OpenStack Compute packages that resolve various issues are now available for Red Hat Enterprise Linux OpenStack Platform 7.0 for RHEL 7. 2. Relevant releases/architectures: OpenStack 7.0 Tools for RHEL 7 - noarch Red Hat Enterprise Linux OpenStack Platform 7.0 for RHEL 7 - noarch 3. Description: OpenStack Compute (nova) launches and schedules large networks of virtual machines, creating a redundant and scalable cloud computing platform. Compute provides the software, control panels, and APIs required to orchestrate a cloud, including running virtual machine instances and controlling access through users and projects. A vulnerability was discovered in the way OpenStack Compute (nova) networking handled security group updates; changes were not applied to already running VM instances. A remote attacker could use this flaw to access running VM instances. (CVE-2015-7713) Additional updates include: * The openstack-nova packages have been upgraded to upstream version 2015.1.2. See https://launchpad.net/nova/kilo/2015.1.2 for a complete list of bug fixes and enhancements. (BZ#1274875) * When using huge pages, the back-end memory for a guest was configured as private. This disallowed an external process connected to a vhostuser VIF type to access the QEMU guest's memory, which is required by the QEMU network driver functionality. The memory mappings are now marked as shared, and the external process to provide QEMU network is able to access the guest's memory. (BZ#1215790) * The termination of a WSGI application or an RPC server immediately stopped the service and interrupted requests that were in progress. This update adds a graceful handler for the SIGTERM signal sent to the parent WSGI process, so the termination is performed gracefully, which allows ongoing processes to continue. (BZ#1250269) * Previously, novaclient records requested time even when timing was set to False. As a consequence, system memory kept increasing. With this update, when timing is set to True, the time of each request is recorded and the timings are reset to clear the memory, which no longer increases. (BZ#1260868) * An earlier update changed the return value when no host devices were found when connecting to an iSCSI or iSER volume. Consequently, when no host devices were found, an exception was thrown and the connect volume attempt failed. This update adds an additional check to ensure os.path.exists(None) is never called. As a result, an exception is no longer thrown and the connect logic correctly retries finding present host devices. (BZ#1268051) * Compute's rootwrap filters restricted an `ln` command used by the volume encryption providers to a specific iSCSI related target path. Consequently, iSER, NFS, and FC volumes encountered failures because the `ln` command was rejected by Compute's rootwrap filters. This update makes Nova's rootwrap filters more generic when calling `ln` allowing the volume encryption providers to succeed. (BZ#1273466) * FCoE devices have different sysfs paths to standard FC devices. Consequently, Nova failed when attempting to attach an FCoE based volume to an instance as it assumed these paths were the same. This update ensures that the required PCI information is parsed from both FC and FCoE sysfs device paths. As a result, Nova now succeeds in attaching FCoE based volumes to instances. (BZ#1274054) * Nova failed to parse the output from the `multipath -l ${device}` command when errors were present. Consequently, the attaching and detaching of volumes could fail. This update corrects the find_multipath_device method to ensure that any errors present in the output from the aforementioned command are ignored. As a result, both the attaching and detaching of volumes will now succeed even if errors occur. (BZ#1275937) * Volumes were not correctly detached if an error was encountered during the attach process, and could be left attached to an instance, resulting in data loss. This update ensures that the volume is both detached and the connection to the volume closed in the event of a failure during the attach process. (BZ#1276011) * The ability of the libvirt driver to set the admin password has been added. To use this feature, run the following command: nova root-password [server] (BZ#1261100) 4. Solution: Before applying this update, ensure all previously released errata relevant to your system have been applied. Red Hat Enterprise Linux OpenStack Platform 7 runs on Red Hat Enterprise Linux 7.2. The Red Hat Enterprise Linux OpenStack Platform 7 Release Notes contain the following: * An explanation of the way in which the provided components interact to form a working cloud computing environment. * Technology Previews, Recommended Practices, and Known Issues. * The channels required for Red Hat Enterprise Linux OpenStack Platform 7, including which channels need to be enabled and disabled. The Release Notes are available at: https://access.redhat.com/documentation/en/red-hat-enterprise-linux-opensta ck-platform/version-7/release-notes/ This update is available through 'yum update' on systems registered through Red Hat Subscription Manager.
