|
|
-----------------
|
|
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=001b ss=0023 ds=0023 es=0023 fs=003b gs=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
|

|
|
cs=001b ss=0023 ds=0023 es=0023 fs=003b gs=0000 efl=00010206
|
|
MFC80+0x23a31:
|
|
781f3a31 8b07 mov eax,dword ptr [edi] ds:0023:61616161=????????
|
|
781f3a33 8bcf mov ecx,edi
|
|

or
