"The remote Red Hat host is missing one or more security updates for Red Hat OpenStack Platform director.");
  script_set_attribute(attribute:"description", value:
"The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as
referenced in the RHSA-2018:1593 advisory.

    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)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
