In this course, we will discuss buffer overflows and integer over- and underflow vulnerabilities, their exploitation and mitigation. Our first module will focus on buffer overflow vulnerabilities, which are some of the simplest vulnerabilities that can exist in an application. This course discusses how poor memory management can leave an application open to attack, how the vulnerability can be exploited and potential mitigations to reduce the probability and impact of vulnerable code. Our second module focuses on Integer overflow and underflow vulnerabilities, which are caused by misuse of the various types of variables available in most programming languages. Understanding how to identify these vulnerabilities and how they can be exploited can prevent an attacker from bypassing checks or triggering other vulnerabilities (like buffer overflows).
