    <p>
    phpBB is vulnerable to a cross-site scripting vulnerability due to
    improper sanitization of user supplied input. Coupled with poor
    validation of BBCode URLs which may be included in a forum post, an
    unsuspecting user may follow a posted link triggering the
    vulnerability.
    </p>
  </description>
  <impact type="normal">
    <p>
    Successful exploitation of the vulnerability could cause arbitrary
    scripting code to be executed in the browser of a user.
    </p>
  </impact>
  <workaround>
    <p>
    There are no known workarounds at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All phpBB users should upgrade to the latest version:
    </p>
    <code>
    emerge --sync
    emerge --ask --oneshot --verbose &quot;&gt;=www-apps/phpBB-2.0.15&quot;</code>
  </resolution>
