Calculating stack pivot position:
|
||||
------------------
|
||||
* Overflow stack
|
||||
* Write 0x92 as index
|
||||
* Store that in globalVarX
|
||||
* Pop till back in stack
|
||||
* globalVarX += 0x240
|
||||
* Overflow stack
|
||||
* Write -0x8B (FFFFFF75) as index
|
||||
* Store in globalVarY
|
||||
* Push globalVarY
|
||||
* Push all other globalVars in order (to not overwrite the ones we need for later!)
|
||||
* Push 0s till we get back to the stack
|
||||
* stack pivot position = globalVarY + 0x30 + script_X (where script_X is the rest of the ROP chain)
|
||||
|
||||
stack+0x574 = first return address for the ROP chain
