Solution
The attack that injects code into dynamically allocated memory is option A: Heap spraying.
Here's a step-by-step explanation:
-
Heap spraying is a technique used in exploits to facilitate arbitrary code execution.
-
In a heap spraying attack, a large amount of non-executable memory is allocated (the "heap").
-
This heap is then filled with the attacker's payload, which is the code they want to execute.
-
The attacker then attempts to exploit a vulnerability that allows them to overwrite a certain memory pointer.
-
The overwritten pointer is made to point to the sprayed heap.
-
Because the heap contains the attacker's payload and the pointer now points to this location, the payload code is executed when the pointer is dereferenced.
So, heap spraying is the attack that involves injecting code into dynamically allocated memory.
