Detailed explanation-1: -In information security and programming, a buffer overflow, or buffer overrun, is an anomaly whereby a program, while writing data to a buffer, overruns the buffer’s boundary and overwrites adjacent memory locations.
Detailed explanation-2: -A buffer overflow occurs when a program or process attempts to write more data to a fixed-length block of memory, or buffer, than the buffer is allocated to hold. Buffers contain a defined amount of data; any extra data will overwrite data values in memory addresses adjacent to the destination buffer.
Detailed explanation-3: -Explanation: In a buffer-overflow attack, the extra data that holds some specific instructions in the memory for actions is projected by a cyber-criminal or penetration tester to crack the system.
Detailed explanation-4: -Key Concepts of Buffer Overflow This error occurs when there is more data in a buffer than it can handle, causing data to overflow into adjacent storage. This vulnerability can cause a system crash or, worse, create an entry point for a cyberattack. C and C++ are more susceptible to buffer overflow.
Detailed explanation-5: -Buffer overflow, or buffer overrun, is an anomaly where a process stores data in a buffer outside the memory the programmer has set aside for it. The extra data overwrites adjacent memory, which may contain other data including program variables and program flow control data.
