'Name' => 'eSignal and eSignal Pro <= 10.6.2425.1208 file parsing buffer overflow in QUO',

'Description'=> %q{

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.
