A buffer overflow occurs when a program or process attempts to write more data to a fixed-length block of memory or buffer, which the buffer is allocated to hold. Because buffers are created to contain a defined amount of data, additional data may overwrite the data values in memory addresses adjacent to the destination buffer unless the program includes enough bounds checking to mark or discard data when it is sent too much to a memory buffer.
The buffer overflow attack was discovered in piracy circles. Uses entries for a badly implemented application, but (intentionally) completely harmless, usually with root / admin privileges. The buffer overflow attack is the result of an entry that is longer than the one implemented. To understand their inner workings, we need to talk a little about how computers use memory.
