Security Fix: * A Cross-Site Request Forgery 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. * 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. These issues were discovered by Martin Prpic .
