  <background>
    <p>Puppet is a system configuration management tool written in Ruby.</p>
  </background>
  <description>
    <p>Multiple vulnerabilities have been found in Puppet:</p>
    
    <ul>
      <li>Puppet uses predictable file names for temporary files
        (CVE-2012-1906).
      </li>
      <li>REST requests for a file in a remote filebucket are not handled
        properly by overriding filebucket storage locations (CVE-2012-1986).
      </li>
      <li>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).
      </li>
      <li>File name paths are not properly sanitized from bucket requests
        (CVE-2012-1988).
      </li>
      <li>The Telnet utility in Puppet does not handle temporary files securely
        (CVE-2012-1989).
      </li>
    </ul>
  </description>
  <impact type="high">
    <p>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. 
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All Puppet users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=app-admin/puppet-2.7.13"
    </code>
