Course description

Managing memory usage has long been a requirement for application development. Unfortunately, most developers don’t do it very well. This can lead to leaks, overflows and crashes in your app. Hackers can exploit these vulnerabilities with denial-of-service and remote code execution attacks. In this course, you will learn how Android mobile app memory is structured and used. You will learn about the most common overflow types and the errors that cause them, and how to avoid them. You will explore what pointers are, the various types of pointers and when and how Android uses pointers. You will also exploit a notorious buffer overflow vulnerability in Stagefright, Android’s media player.
