Scientific Linux Security Update : pcs on SL6.x, SL7.x i386/x86_64

High Nessus Plugin ID 85760


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


A command injection flaw was found in the pcsd web UI. An attacker able to trick a victim that was logged in to the pcsd web UI into visiting a specially crafted URL could use this flaw to execute arbitrary code with root privileges on the server hosting the web UI.

A race condition was found in the way the pcsd web UI backend performed authorization of user requests. An attacker could use this flaw to send a request that would be evaluated as originating from a different user, potentially allowing the attacker to perform actions with permissions of a more privileged user. (CVE-2015-5189)


Update the affected pcs, pcs-debuginfo and / or python-clufter packages.
