Crashing ISPSoft

Few days ago I decided to fuzz a little bit one software available at Delta Electronics web page. This software is called ISPSoft and you can find it here. Below few quick results...
You can read about it here:

When software is installed and ready to use we can grab our sample file(s) and try to open it in ISPSoft (I used Windbg). Both cases below:

Case #01:

---<windbg>---
 eax=0ada8a46 ebx=0ad6301c ecx=00000000 edx=00028a46 esi=00000058 edi=00000055
eip=0ad19cc4 esp=0032ee2c ebp=0032ee54 iopl=0         nv up ei pl nz na po nc
cs=001b  ss=0023  ds=0023  es=0023  fs=003b  gs=0000             efl=00010202
DelZip179!DllEntryPoint+0x56b8:
0ad19cc4 8a08            mov     cl,byte ptr [eax]          ds:0023:0ada8a46=??

---<windbg>---




Case #02:

---<windbg>---
eax=0a248a43 ebx=00000100 ecx=0a671c16 edx=00000101 esi=00000200 edi=000150c4
eip=0a64afcd esp=0032e868 ebp=0032ee48 iopl=0         nv up ei pl nz na po nc
cs=001b  ss=0023  ds=0023  es=0023  fs=003b  gs=0000             efl=00010202
DelZip179!DllEntryPoint+0x69c1:
0a64afcd 8a1441          mov     dl,byte ptr [ecx+eax*2]    ds:0023:1eb0309c=??

---<windbg>--- 

Both cases you can find here.

Maybe you'll find it useful.

Cheers
