  <description>
    <p>A command injection vulnerability in Nokogiri allows commands to be
      executed in a subprocess by Ruby’s Kernel.open method. Processes are
      vulnerable only if the undocumented method
      Nokogiri::CSS::Tokenizer#load_file is being passed untrusted user input.
    </p>
  </description>
  <impact type="normal">
    <p>A remote attacker could possibly execute arbitrary code with the
      privileges of the process.
    </p>
  </impact>
  <workaround>
    <p>Avoid calling the undocumented method Nokogiri::CSS::Tokenizer#load_file
      with untrusted user input.
    </p>
  </workaround>
  <resolution>
    <p>All Nokogiri users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=dev-ruby/nokogiri-1.10.4"
    </code>
