Scientific Linux Security Update : pcs on SL7.x x86_64

Medium Nessus Plugin ID 95853


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


The following packages have been upgraded to a newer upstream version:
pcs (0.9.152).

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.

- 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).

Additional Changes :


Update the affected pcs and / or pcs-debuginfo packages.
