pcs security update

CentOS Errata and Security Advisory CESA-2016:2596

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).
