Why do buffer overflows happen?
Beside this, how are buffer overflows exploited?
Buffer overflow is probably the best known form of software security vulnerability. In a classic buffer overflow exploit, the attacker sends data to a program, which it stores in an undersized stack buffer. The result is that information on the call stack is overwritten, including the function's return pointer.
Similarly, is buffer overflow still a problem? Buffer overflow, a very dangerous kind of security vulnerability, has been haunting software developers and security experts for decades. At its core, buffer overflow is a very simple bug, but despite advances to security software and computer code security tools, it remains a source of concern.
Regarding this, what is a buffer overflow example?
In a buffer-overflow attack, the extra data sometimes holds specific instructions for actions intended by a hacker or malicious user; for example, the data could trigger a response that damages files, changes data or unveils private information.

A stack buffer overflow occurs when the targeted buffer is located on the stack, usually as a local variable in a function's stack frame.
