    <p>
    DokuWiki is a simple to use wiki targeted at developer teams,
    workgroups and small companies.

  <description>
    <p>
    Stefan Esser discovered that the DokuWiki spell checker fails to
    properly sanitize PHP's "complex curly syntax".
    </p>
  </description>
  <impact type="high">
    <p>
    A unauthenticated remote attacker may execute arbitrary PHP commands -
    and thus possibly arbitrary system commands - with the permissions of
    the user running the webserver that serves DokuWiki pages.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All DokuWiki users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=www-apps/dokuwiki-20060309-r1&quot;</code>
  </resolution>
