Buffer overflow attacks are attacks in which an attacker submits data to a system that exceeds the storage capacity of the memory buffer in which that data is supposed to be stored, thereby causing the system to overwrite other memory with the data the user submitted. Carefully crafted buffer overflow input by an attacker, for example, could overwrite memory space in which the system is storing commands that it will execute per the instructions of its authorized user — perhaps even replacing such commands with commands the attacker wants the system to execute.
