    </p>
  </description>
  <impact type="normal">
    <p>A remote attacker could entice a user to open a specially crafted index
      file using Python’s dumbdbm module, possibly resulting in execution of
      arbitrary code with the privileges of the process.
    </p>
    
    <p>A remote attacker could entice a user to process a specially crafted
      input stream using Python’s zipimporter module, possibly allowing
      attackers to cause unspecified impact.
    </p>
    
    <p>A man in the middle attacker could strip out the STARTTLS command
      without generating an exception on the Python SMTP client application,
      preventing the establishment of the TLS layer.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All Python 2 users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=dev-lang/python-2.7.12:2.7"
    </code>
    
    <p>All Python 3 users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=dev-lang/python-3.4.5:3.4"
    </code>
