"A Buffer overflow" vulnerability exploit resulted from the attacker's actions.
Whenever a software or an application writes too much data into a buffer, causing neighboring storage regions to have been corrupted as a consequence, this could be determined as Buffer overflow.
⇒ There are two kinds of Buffer overflow attacks such as:
- <u>Stack-based</u> - It will become more popular to use such memory, as well as that's only available during implementation of any code.
- <u>Heap-based</u> - Those attacks seem to be more difficult to execute because they entail overflowing overall storage capacity allotted for a program further than the space needed for something like the program's present activities.
Thus we can say that the correct answer is a Buffer overflow.
