CFI: Control Flow Integrity or Control Flow Interruption?

open access: yes2019 IEEE East-West Design & Test Symposium (EWDTS), 2019
Runtime memory vulnerabilities, especially present in widely used languages as C and C++, are exploited by attackers to corrupt code pointers and hijack the execution flow of a program running on a target system to force it to behave abnormally. This is the principle of modern Code Reuse Attacks (CRAs) and of famous attack paradigms as Return-Oriented ...
