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.

<workaround>
|
|
<p>
|
|
There is no known workaround at this time.

</workaround>

<resolution>
|
|
<p>
|
|
All HTMLDOC users should upgrade to the latest version:
|
|

|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=app-text/htmldoc-1.8.27-r1"</code>
