Red Hat Security Advisory 2018-0315-01

Red Hat Security Advisory 2018-0315-01
Posted Feb 13, 2018
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2018-0315-01 - openstack-aodh provides the ability to trigger actions based on defined rules against metric or event data collected by OpenStack Telemetry or Time-Series-Database-as-a-Service. openstack-aodh has been rebased to the upstream 4.0.2-3 version. Security Fix: 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.
