Red Hat Security Advisory

 

Synopsis: Important: puppet security update

Advisory ID: RHSA-2013:0710-01

Product: Red Hat OpenStack

Advisory URL: https://rhn.redhat.com/errata/RHSA-2013-0710.html

Issue date: 2013-04-04

CVE Names: CVE-2012-6120 CVE-2013-1640 CVE-2013-1652

CVE-2013-1654 CVE-2013-2274 CVE-2013-2275

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

 

1. Summary:

 

Updated puppet packages that fix several security issues are now available

for Red Hat OpenStack Folsom.

 

The Red Hat Security Response Team has rated this update as having

important security impact. Common Vulnerability Scoring System (CVSS) base

scores, which give detailed severity ratings, are available for each

vulnerability from the CVE links in the References section.

 

2. Relevant releases/architectures:

 

OpenStack Folsom - noarch

 

3. Description:

 

Puppet allows provisioning, patching, and configuration of clients to be

managed and automated.

 

A flaw was found in how Puppet handled certain HTTP PUT requests. An

attacker with valid authentication credentials, and authorized to save to

the authenticated client's own report, could construct a malicious request

that could possibly cause the Puppet master to execute arbitrary code.

(CVE-2013-2274)

 

A flaw was found in how Puppet handled the "template" and "inline_template"

functions during catalog compilation. If an authenticated attacker were to

requests its catalog from the Puppet master, it could possibly result in

arbitrary code execution when the catalog is compiled. (CVE-2013-1640)

 

A flaw was found in how Puppet handled certain HTTP GET requests. An

attacker with valid authentication credentials could construct a request to

retrieve catalogs from the Puppet master that they are not authorized to

access. (CVE-2013-1652)

 

It was found that the default /etc/puppet/auth.conf configuration file

allowed an authenticated node to submit a report for any other node, which

could breach compliance requirements. (CVE-2013-2275)

 

It was found that the /var/log/puppet directory was created world-readable.

This could allow local users to obtain sensitive information from the

Puppet log files. (CVE-2012-6120)

 

It was found that Puppet allowed the use of the SSLv2 protocol. A Puppet

agent could use this to negotiate the use of the weak SSLv2 protocol for

its connection to a Puppet master. (CVE-2013-1654)

 

Red Hat would like to thank Puppet Labs for reporting CVE-2013-1640,

CVE-2013-1652, CVE-2013-1654, CVE-2013-2274, and CVE-2013-2275.

 

Note: In most default configurations these issues are not directly

exploitable unless the attacker has access to the underlying OpenStack

infrastructure (e.g. shell access to a Nova compute node).

 

Users of Red Hat OpenStack Folsom are advised to upgrade to these updated

packages, which upgrade Puppet to version 2.6.18 and correct these issues.

 

4. Solution:
