<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.

<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 &quot;&gt;=app-text/htmldoc-1.8.27-r1&quot;</code>
