What is Buffer Overflow in Cybersecurity?
A vulnerability that occurs when a program writes more data to a memory buffer than it can hold, overwriting adjacent memory. Attackers craft inputs that overflow the buffer to inject and execute malicious code or crash the application. Buffer overflows have been behind some of the most damaging exploits in history.
Why Buffer Overflow Matters for Your Cybersecurity Career
Buffer overflows are a foundational concept tested on the OSCP and other cybersecurity certifications. Penetration testers write buffer overflow exploits to demonstrate critical vulnerabilities. Security engineers implement protections like ASLR and DEP to prevent exploitation. Understanding memory corruption separates entry-level from advanced security professionals.
