Red Hat Security Advisory

Synopsis: Moderate: Red Hat OpenStack Platform director security update
Advisory ID: RHSA-2018:1593-01
Product: Red Hat Enterprise Linux OpenStack Platform
Advisory URL:
Issue date: 2018-05-17
CVE Names: CVE-2017-12155 CVE-2018-1000115

1. Summary:

An update is now available for Red Hat OpenStack Platform 10.0 (Newton).

Red Hat Product Security has rated this update as having a security impact
of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available for each vulnerability from
the CVE link(s) in the References section.

2. Relevant releases/architectures:

Red Hat OpenStack Platform 10.0 – noarch

3. Description:

Red Hat OpenStack Platform director provides the facilities for deploying
and monitoring a private or public infrastructure-as-a-service (IaaS) cloud
based on Red Hat OpenStack Platform.

Security Fix(es):

* A resource-permission flaw was found in the python-tripleo and
openstack-tripleo-heat-templates packages where
ceph.client.openstack.keyring is created as world-readable. A local
attacker with access to the key could read or modify data on Ceph cluster
pools for OpenStack as though the attacker were the OpenStack service, thus
potentially reading or modifying data in an OpenStack Block Storage volume.

To exploit this flaw, the attacker must have local access to an overcloud
node. However by default, access to overcloud nodes is restricted and
accessible only from the management undercloud server on an internal
network. (CVE-2017-12155)

This issue was discovered by Katuya Kawakami (NEC).

* It was discovered that the memcached connections using UDP transport
protocol can be abused for efficient traffic amplification distributed
denial of service (DDoS) attacks. A remote attacker could send a malicious
UDP request using a spoofed source IP address of a target system to
memcached, causing it to send a significantly larger response to the
target. (CVE-2018-1000115)

This advisory also addresses the following issues:

* This release adds support for deploying Dell EMC VMAX Block Storage
backend using the Red Hat OpenStack Platform director. (BZ#1503896)

* Using composable roles for deploying Dell SC and PS Block Storage backend
caused errors. The backends could only be deploying using
‘cinder::config::cinder_config’ hiera data.
With this update, the composable role support for deploying the Dell SC and
PS Block Storage backends is updated. As a result, they can be now deployed
using composable roles. (BZ#1552980)

* Previously, the iptables rules were managed by the Red Hat OpenStack
Platform director and the OpenStack Networking service, which resulted in
the rules created by the OpenStack Networking service to persist on to the
disk. As a result, the rules that should not be loaded after an iptables
restart or a system reboot would be loaded causing traffic issues.
With this update, the Red Hat OpenStack Platform director has been updated
to exclude the OpenStack Networking rules from ‘/etc/sysconfig/iptables’
when the director saves the firewall rules. As a result, iptables restart
or a system reboot should work without causing traffic problems.
Note: It might be necessary to perform a rolling restart of the controller
nodes to ensure that any orphaned managed neutron rules are no longer
reloaded. (BZ#1541528)

* OS::TripleO::SwiftStorage::Ports* resources have been renamed to
OS::TripleO::ObjectStorage::Port* to ensure standalone Object Storage nodes
using the ‘ObjectStorage’ roles can be deployed correctly. Operators need
to modify their custom templates that previously used
OS::TripleO::SwiftStorage::Ports* settings. (BZ#1544802)
