Description:
An integer overflow attack occurs when an arithmetic operation attempts to create a numeric value that is outside the range that can be represented with a given number of bits. For example, in systems where an integer is represented by a fixed size (like 32 bits), trying to store a value that exceeds the maximum value that can be held leads to an overflow. This overflow can cause unexpected behavior, potentially leading to vulnerabilities where an attacker can exploit these conditions to execute malicious code, alter permissions, or cause a system to crash.

Use-cases of Integer Overflow Attack include:
Buffer Overflow: An attacker might use an integer overflow to specify a buffer size that leads to a buffer overflow, allowing the execution of arbitrary code.
Memory Allocation Errors: Incorrect size calculations due to integer overflow can lead to insufficient memory allocation, resulting in memory corruption.
Denial of Service (DoS): By causing an application to crash through integer overflow, attackers can render services unavailable.
