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.
