The remote Red Hat host is missing one or more security updates.
Updated pcs packages that fix one security issue and one bug are now
available for Red Hat Enterprise Linux 6.
Red Hat Product Security has rated this update as having Important
security impact. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available from the
CVE link in the References section.
The pcs packages provide a command-line tool and a web UI to configure
and manage the Pacemaker and Corosync tools.
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.
This issue was discovered by Tomas Jelinek of Red Hat.
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. (BZ#1212115)
All pcs users are advised to upgrade to these updated packages, which
contain backported patches to correct these issues. After installing
the updated packages, the pcsd daemon will be restarted automatically.
