"An update for heketi is now available for Red Hat Gluster Storage 3.3
for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security
impact of Important. 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.

Heketi provides a RESTful management interface which can be used to
manage the life cycle of GlusterFS volumes. With Heketi, cloud
services like OpenStack Manila, Kubernetes, and OpenShift can
dynamically provision GlusterFS volumes with any of the supported
durability types. Heketi will automatically determine the location for
bricks across the cluster, making sure to place bricks and its
replicas across different failure domains. Heketi also supports any
number of GlusterFS clusters, allowing cloud services to provide
network file storage without being limited to a single GlusterFS
cluster.

Security Fix(es) :

* A security-check flaw was found in the way the Heketi server API
handled user requests. An authenticated Heketi user could send
specially crafted requests to the Heketi server, resulting in remote
command execution as the user running Heketi server and possibly
privilege escalation. (CVE-2017-15103)

* An access flaw was found in heketi, where the heketi.json
configuration file was world readable. An attacker having local access
to the Heketi server could read plain-text passwords from the
heketi.json file. (CVE-2017-15104)

Red Hat would like to thank Markus Krell (NTT Security) for reporting
CVE-2017-15103. The CVE-2017-15104 issue was discovered by Siddharth
Sharma (Red Hat)."
