    <p>
    ANTHRAX666 reported an insecure call to the sscanf() function in the
    set_page_size() function in htmldoc/util.cxx. Nico Golde of the Debian
    Security Team found two more insecure calls in the write_type1()
    function in htmldoc/ps-pdf.cxx and the htmlLoadFontWidths() function in
    htmldoc/htmllib.cxx.
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could entice a user to process a specially crafted
    HTML file using htmldoc, possibly resulting in the execution of
    arbitrary code with the privileges of the user running the application.
    NOTE: Additional vectors via specially crafted AFM font metric files do
    not cross trust boundaries, as the files can only be modified by
    privileged users.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All HTMLDOC users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=app-text/htmldoc-1.8.27-r1"</code>
