DEF

An attack in which a malicious user exploits an unchecked buffer in a program and overwrites the program code with their own data.

CONT

Buffer overflow: A threat actor could overflow a memory buffer using a simple string-copying or print function, which works because the function didn't check the buffer length before executing it. The attacker then overwrites the return address and points it to a shellcode in the buffer, causing the shellcode to be executed in place of the regular program.
