Updated openstack-ironic-discoverd packages that fix one security issue are
now available for Red Hat Enterprise Linux OpenStack Platform 6.0.

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

Description

OpenStack Bare Metal (ironic) is a tool used to provision bare metal
(as opposed to virtual) machines. It leverages common technologies such
as PXE boot and IPMI to cover a wide range of hardware. It also supports
pluggable drivers to allow added, vendor-specific functionality.

It was discovered that enabling debug mode in openstack-ironic-discoverd
also enabled debug mode in the underlying Flask framework. If errors were
encountered while Flask was in debug mode, a user experiencing an error
might be able to access the debug console (effectively, a command shell).
(CVE-2015-5306)

Please note that this package is a Technology Preview and should not be
used in production.

All openstack-ironic-discoverd users are advised to upgrade to these
updated packages, which correct this issue.
