2) Bugs
=======

-----------------
A] code execution
-----------------

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:

eax=00000001 ebx=00000000 ecx=61616161 edx=02830000 esi=0012f020 edi=03ed97f0
eip=61616161 esp=0012efb8 ebp=0012f088 iopl=0 nv up ei pl nz ac po nc
cs=001bss=0023ds=0023es=0023fs=003bgs=0000 efl=00010212
61616161 ?????


----------------
B] heap overflow
----------------

Heap overflow during the handling of the Font->FaceName field of the
various files that use it like ETS, ETQ, ESK and so on:

eax=04255aa8 ebx=0012f004 ecx=04255ab4 edx=61616160 esi=0012f004 edi=61616161
