Heap Overflow thecniques
Say i want to lunch a heap overflow attack.
Many times I need to control aa series of allocations and free's 
In order to make a successfull attack.
My question is how, as an attacker, can I control allocations
In such a precise way so that my attack will succeed.

I would love a real life example how such an attack
Can be practically luanched, Thanks.
