Synopsis
========

Multiple vulnerabilities have been found in Puppet, the worst of which
could lead to execution of arbitrary code.

Background
==========

Puppet is a system configuration management tool written in Ruby.

Affected packages
=================

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  app-admin/puppet             < 2.7.13                  >= 2.7.13

Description
===========

Multiple vulnerabilities have been found in Puppet:

* Puppet uses predictable file names for temporary files
  (CVE-2012-1906).
* REST requests for a file in a remote filebucket are not handled
  properly by overriding filebucket storage locations (CVE-2012-1986).
* REST requests for a file in a remote filebucket are not handled
  properly by reading streams or writing files on the Puppet master's
  file system (CVE-2012-1987).
* File name paths are not properly sanitized from bucket requests
  (CVE-2012-1988).
* The Telnet utility in Puppet does not handle temporary files securely
  (CVE-2012-1989).

Impact
======

A local attacker with access to agent SSL keys could possibly execute
arbitrary code with the privileges of the process, cause a Denial of
Service condition, or perform symlink attacks to overwrite or read
arbitrary files on the Puppet master.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Puppet users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=app-admin/puppet-2.7.13"
