Defending C Applications Against Use After Free

Use After Free vulnerabilities arise when memory is deallocated before being accessed by unmanaged code. Attackers might exploit these holes to run wild codes, leading to many problems, such as crashing the system. Thus, resetting the pointers as null upon freeing their linked memory is necessary. Consequently, it is also essential to check for null pointers before using them in case they could be pointing at random locations in the system memory. This Defending C Applications Against Use After Free Skill Lab offers a virtual environment that includes a vulnerable application and its complete source code to train developers on identifying and addressing Use After Free vulnerabilities.
