                   Red Hat Security Advisory

Synopsis:          Moderate: openstack-aodh security update
Advisory ID:       RHSA-2018:0315-01
Product:           Red Hat Enterprise Linux OpenStack Platform
Advisory URL:      https://access.redhat.com/errata/RHSA-2018:0315

CVE Names:         CVE-2017-12440 
=====================================================================

1. Summary:

An update for openstack-aodh is now available for Red Hat OpenStack
Platform 11.0 (Ocata).

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 11.0 - noarch

3. Description:

openstack-aodh provides the ability to trigger actions based on defined
rules against metric or event data collected by OpenStack Telemetry
(ceilometer) or Time-Series-Database-as-a-Service (gnocchi).

openstack-aodh has been rebased to the upstream 4.0.2-3 version.

Security Fix(es):

* A verification flaw was found in openstack-aodh. As part of an HTTP alarm
action, a user could pass in a trust ID. However, the trust could be from
anyone because it was not verified. Because the trust was then used by
openstack-aodh to obtain a keystone token for the alarm action, a malicious
user could pass in another person's trust ID and obtain a keystone token
containing the delegated authority of that user. (CVE-2017-12440)

Red Hat would like to thank the OpenStack project for reporting this issue.
Upstream acknowledges Zane Bitter (Red Hat) as the original reporter.
