LAB 347 – Defending C Applications Against Null Pointer Dereference (NEW)

Course Overview

Null Pointer Dereference vulnerabilities pose a significant risk, causing application crashes or, in rare cases, arbitrary code execution when an application attempts to use a null pointer. This Skill Lab offers hands-on experience identifying and mitigating such vulnerabilities within C applications. By validating pointers before accessing the associated memory, developers can overcome these issues. The virtual environment provides a vulnerable application and its complete source code, facilitating practical training to address Null Pointer Dereference concerns effectively.

After completing this lab, the learner will understand how to defend C applications against Null Pointer Dereference vulnerabilities by validating pointers and implementing appropriate mitigation techniques to ensure application stability and security.
