A usual buffer overflow attack sends the server a message which not just overwrites a return address but also includes the code the attacker wants to execute. The return address would be overwritten to point tomake the code inprogram jump into the message itself which will then be interpreted as code and executed.

Sometimes there is not enough space for the complete shellcode. In that case the attacker might use other methods to place their shellcode in a known memory location. This can be done by sending data to non-vulnerable functions which store thearen't vulnerable them self but accept larger amounts of data they receiveand store it in a predictable memory location.
