    <package name="dev-lang/wml" auto="yes" arch="*">
      <unaffected range="ge">2.0.11-r3</unaffected>

    HTML generation toolkit for Unix.

  <description>
    <p>
    Temporary files are handled insecurely in the files
    wml_backend/p1_ipp/ipp.src, wml_contrib/wmg.cgi, and
    wml_backend/p3_eperl/eperl_sys.c, allowing users to overwrite or delete
    arbitrary files with the privileges of the user running the program.
    </p>
  </description>
  <impact type="normal">
    <p>
    Local users can exploit the insecure temporary file vulnerabilities via
    symlink attacks to perform certain actions with escalated privileges.
    </p>
  </impact>
  <workaround>
    <p>
    Restrict access to the temporary directory to trusted users only.
    </p>
  </workaround>
  <resolution>
    <p>
    All Website META Language users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=dev-lang/wml-2.0.11-r3&quot;</code>
  </resolution>
