                   Red Hat Security Advisory

Synopsis:          Important: heketi security update
Advisory ID:       RHSA-2017:3481-01
Product:           Red Hat Gluster Storage
Advisory URL:      https://access.redhat.com/errata/RHSA-2017:3481
Issue date:        2017-12-18
CVE Names:         CVE-2017-15103 CVE-2017-15104 
=====================================================================

1. Summary:

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.

2. Relevant releases/architectures:

Red Hat Gluster Storage Server 3.3 on RHEL-7 - x86_64

3. Description:

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).
