  <description>
    <p>When PHPUnit is installed in a production environment via composer and
      these modules are in a web accessible directory, the eval-stdin.php file
      in PHPUnit contains vulnerable statements that trigger the vulnerability.
    </p>
  </description>
  <impact type="normal">
    <p>A remote attacker could possibly execute arbitrary PHP code or cause a
      Denial of Service condition.
    </p>
  </impact>
  <workaround>
    <p>There are several ways to fix or mitigate this vulnerability:</p>
    
    <p>Remove PHPUnit from the production environment.</p>
    
    <p>Update PHPUnit.</p>
    
    <p>Manually apply the patch.</p>
    
    <p>Disable direct access to the composer packages by placing .htaccess file
      to /vendor folder.
    </p>
  </workaround>
  <resolution>
    <p>All PHPUnit users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=dev-php/phpunit-5.7.15-r1"
