Synopsis: Important: pacemaker security update

Advisory ID: RHSA-2016:2675-01

Product: Red Hat Enterprise Linux

Advisory URL: https://rhn.redhat.com/errata/RHSA-2016-2675.html

Issue date: 2016-11-08

CVE Names: CVE-2016-7035

=====================================================================

 

1. Summary:

 

An update for pacemaker is now available for Red Hat Enterprise Linux 6.

 

Red Hat Product Security has rated this update as having a security impact

of Important. A Common Vulnerability Scoring System (CVSS) base score,

which gives a detailed severity rating, is available for each vulnerability

from the CVE link(s) in the References section.

 

2. Relevant releases/architectures:

 

Red Hat Enterprise Linux High Availability (v. 6) - i386, x86_64

Red Hat Enterprise Linux Resilient Storage (v. 6) - i386, x86_64

 

3. Description:

 

The Pacemaker cluster resource manager is a collection of technologies

working together to provide data integrity and the ability to maintain

application availability in the event of a failure.

 

Security Fix(es):

 

* An authorization flaw was found in Pacemaker, where it did not properly

guard its IPC interface. An attacker with an unprivileged account on a

Pacemaker node could use this flaw to, for example, force the Local

Resource Manager daemon to execute a script as root and thereby gain root

access on the machine. (CVE-2016-7035)

 

This issue was discovered by Jan "poki" Pokorny (Red Hat) and Alain Moulle

(ATOS/BULL).
