cryptxor / fuu Goto Github PK

What steps will reproduce the problem?
1.Double click on the installer
2.Click "next" as many times as needed
3.???
4.PROFIT!

What is the expected output? What do you see instead?

It's expected to see the UAC prompt before the installer is run. Instead no 
prompt is shown, and the installer breaks due to lack of permissions to write 
on the filesystem.

What version of the product are you using? On what operating system?

Latest as of now, downloaded from the project "Downloads" tab. (I haven't 
tested trunk yet).

Erick report that the ASPack plugin does not work with the DLL. (maybe because 
this plugin does not support dll unpacking? :P)

Is seems that current version of the UPX Plugin is not re-building the IAT in 
the correct way.

This issue was reported by ErickSoft.

Por cierto haciendo los cambios en la versión de 64bits he visto un posible 
error en la de 32bits, concretamente en esta parte

invoke IsDlgButtonChecked, hWin, RealignPECheckBox
.if eax != TRUE
   mov eax, dword ptr[OptionsArray]
   mov dword ptr[eax], 0
.endif 
invoke IsDlgButtonChecked, hWin, CopyOverlayDataBt
.if eax != TRUE
mov eax, dword ptr[OptionsArray+4]
mov dword ptr[eax],0
.endif

Primero de todo que no sería TRUE, sería BST_CHECKED
Pero sobre todo que tu partes de la inicialización del vector a 1. Y cuando 
ejecutas el plugin corriges con 0 según esté desmarcada la opción.

Si no cierro el FUU, cambio las opciones y vuelvo a ejecutar un plugin, los 
cambios no se quedan reflejados. 

En 64bits he cambiado esto por:

invoke IsDlgButtonChecked, hWin, RealignPECheckBox
@IF <<cmp eax,BST_CHECKED>>,EQUAL?  
mov rax, qword ptr[OptionsArray]
mov dword ptr[rax],1
@ELSE
mov rax, qword ptr[OptionsArray]
mov dword ptr[rax],0
@ENDIF
invoke IsDlgButtonChecked, hWin, CopyOverlayDataBt
@IF<<cmp eax,BST_CHECKED>>,EQUAL?
mov rax, qword ptr[OptionsArray+8]
mov dword ptr[rax],1
@ELSE
mov rax, qword ptr[OptionsArray+8]
mov dword ptr[rax],0
@ENDIF

note: found by Guan de Dio.

it would be nice and usefull to have a command line version of fuu.

Those UPX versions can't be unpacked with the UPX command line tool, so it'd be 
nice to have them supported in FUU.

An example of a packed binary is the exectuable of the newest version of XChat 
on Windows.
