addres inject
 

Does anybody know how to inject in EBP and EIP addres properly ?
I treid many posiblities ,but it is stil 4bits earlier .

injecting.c

main(){
int i=0;
char stuffing[40];

for (i=0;i<=44;i+=4)
*(long *) &stuffing[i] = 0x080483f5;
puts(stuffing);
}


then

sh#: (./injecting;cat)|./recieving

core dumped

sh#:gdb recieving core dump

Code injection falls into a pretty shady category, with the potential to be in violation of LQ Rules. Hacking/cracking/exploiting are not welcome topics of discussion here.

It may make no difference what your response is, but for a few minutes, I'll give you the benefit of the doubt: what is the purpose/intent of what you are attempting to do here?
