                   Red Hat Security Advisory

Synopsis:          Moderate: pcs security, bug fix, and enhancement update
Advisory ID:       RHSA-2016:2596-02
Product:           Red Hat Enterprise Linux
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2016-2596.html
Issue date:        2016-11-03
CVE Names:         CVE-2016-0720 CVE-2016-0721 
=====================================================================

1. Summary:

An update for pcs is now available for Red Hat Enterprise Linux 7.

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 Enterprise Linux Server High Availability (v. 7) - s390x, x86_64
Red Hat Enterprise Linux Server Resilient Storage (v. 7) - s390x, x86_64

3. Description:

The pcs packages provide a command-line configuration system for the
Pacemaker and Corosync utilities.

The following packages have been upgraded to a newer upstream version: pcs
(0.9.152). (BZ#1299847)

Security Fix(es):

* A Cross-Site Request Forgery (CSRF) flaw was found in the pcsd web UI. A
remote attacker could provide a specially crafted web page that, when
visited by a user with a valid pcsd session, would allow the attacker to
trigger requests on behalf of the user, for example removing resources or
restarting/removing nodes. (CVE-2016-0720)

* It was found that pcsd did not invalidate cookies on the server side when
a user logged out. This could potentially allow an attacker to perform
session fixation attacks on pcsd. (CVE-2016-0721)

These issues were discovered by Martin Prpic (Red Hat Product Security).

Additional Changes:

For detailed information on changes in this release, see the Red Hat
Enterprise Linux 7.3 Release Notes linked from the References section.
