RHEL 7 : pcs (RHSA-2016:2596)

This script is Copyright (C) 2016-2017 Tenable Network Security, Inc.


Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

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.

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.
