Scientific Linux Security Update : pcs on SL6.x i386/srpm/x86_64

This script is Copyright (C) 2015 Tenable Network Security, Inc.


Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

It was found that the pcs daemon did not sign cookies containing
session data that were sent to clients connecting via the pcsd web UI.
A remote attacker could use this flaw to forge cookies and bypass
authorization checks, possibly gaining elevated privileges in the pcsd
web UI. Note: the pcsd web UI is not enabled by default.
(CVE-2015-1848)

This update also fixes the following bug :

- When the IPv6 protocol was disabled on a system,
starting the pcsd daemon on this system previously
failed. This update adds the ability for pcsd to fall
back to IPv4 when IPv6 is not available. As a result,
pcsd starts properly and uses IPv4 if IPv6 is disabled.

After installing the updated packages, the pcsd daemon will be
restarted automatically.
