Insight
Insight
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. (CVE-2015-1848) 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.
