Exam SY0-501 topic 1 question 804 discussion

A buffer overflow either followed by a DoS or an arbitrary code execution. … If the attacker uses the buffer overflow to crash the system or disrupt its services, it is a DoS attack. More often, the attacker’s goal is to insert malicious code in a memory location that the system will execute. … (Darril Gibson’s Get Certified Get Ahead p. 510-511) Since the question says MOST likely, it's A.

A. Why? when there is an overflow into another memory location. An attacker can place her malicious code in that location. Hence an Arbitrary code execution.

buffer overflow An attack in which data goes past the boundary of the destination buffer and begins to corrupt adjacent memory. This can allow the attacker to crash the system or execute arbitrary code.

A buffer overflow occurs when a program or process attempts to write more data to a fixed length block of memory (a buffer), than the buffer is allocated to hold. By sending carefully crafted input to an application, an attacker can cause the application to execute arbitrary code, possibly taking over the machine https://www.coengoedegebure.com/buffer-overflow-attacks-explained/#:~:text=A%20buffer%20overflow%20occurs%20when,possibly%20taking%20over%20the%20machine.

If a bad actor can get a pointer to point incorrectly, a dereference can cause havoc to the code. For example, a null pointer dereference is a common way to try to force a buffer overflow. https://www.youtube.com/watch?v=1S0aBV-Waeo Must be code execution.

Usually, a buffer overflow will create a system crash, so this should be reflected by C.
