Integer Overflow occurs when an arithmetic operation attempts to create a numeric value that exceeds the maximum limit of the data type used to store it. Similarly, Integer Wraparound happens when the numeric value “wraps around”, cycling back to the minimum limit.
In software development, a NULL pointer is a pointer variable that does not reference any valid memory location. Dereferencing such a pointer—attempting to access the memory it supposedly points to—results in undefined behaviour. In many systems, this leads to crashes, data corruption, or even exploitable vulnerabilities.
Insecure deserialisation refers to a scenario where an application deserialises data without validating its integrity or origin. This process, if compromised, can allow attackers to inject code, manipulate data, or trigger unintended operations within an application. For example, if an attacker injects crafted data into the deserialisation process, they could potentially gain control over the application server, extract sensitive information, or cause service disruptions.
