Buffer Overflow

Introduction

A buffer overflow occurs when a program writes more data to a buffer than it can hold, overwriting adjacent memory such as return addresses.

By carefully crafting input, you can redirect execution flow to arbitrary code.

Buffer overflow pattern generator: Web utility for 32‑bit & 64‑bit patterns
Pwntools: cyclic(n) -> generate pattern / cyclic_find(offset) -> find crash offset

Example (64‑bit pattern):

from pwn import *
pattern = cyclic(200)
print(pattern)
