Question

Quizplus · Accepted Answer

An integer overflow attack occurs when an attacker manipulates the value of a variable in such a way that it exceeds its intended range, often resulting in unexpected behavior or security vulnerabilities. This can be achieved by adding or subtracting large values from integers, or by assigning values that are too large to fit into a variable's memory space.
