Description
Buffer overflow is an anomaly where a program, while writing data to a buffer, overruns the buffer's boundary and overwrites adjacent memory. This anomaly has been used maliciously, explicitly to craft exploits. Buffer overflow attacks compose greater than 25% of malware attacks. Without buffer overflow protection enabled, systems are more vulnerable to attacks that attempt to overwrite adjacent memory in the stack frame. Buffer overflow protection is only configurable on non-64-bit systems.
