What is use-after-free in programming?
Use-after-free is a type of vulnerability that occurs when a program continues to use a memory location after it has been freed.
Can you give me an example of how it happens?
Sure! Imagine you have an object in memory, and you free it. If you then try to access that object, you might get unexpected behavior or crashes.
Why is it dangerous?
It's dangerous because attackers can exploit this vulnerability to execute arbitrary code, leading to security breaches.
How can I prevent use-after-free errors?
You can prevent them by using smart pointers in C++, performing thorough memory management, and employing tools like AddressSanitizer.
