Explore binary exploitation techniques in this NDC Oslo 2021 conference talk by Marit Iren and Christian Resell. Gain insights into memory corruption vulnerabilities and their relevance in modern software. Learn about stack overflows, heap exploitation, and memory allocation through code examples and live demonstrations. Witness a real-world exploit of a recent Exim mail server vulnerability, understanding both the vulnerability itself and the exploit process. Discover methods for detecting and preventing memory corruption vulnerabilities in your own software. Engage with concepts such as stack growth, shared library code, and exploit mechanics through practical demonstrations and analogies.
