The early attacker just uploaded (injected) in the target process the code that they wanted to execute and redirected the control flow to that code. Over the years the set of exploiting techniques and the defensive countermeasures required have increased significantly. We conclude that the performance overhead introduced, jointly with the partial attack coverage, is discouraging the industry from adopting most of them.ĭue to continuous improvements in the attacking methods and techniques, a protection technique often becomes outdated and having been required to come up with something more advanced. Our study indicates that the majority of the CFI techniques are primarily focused on restricting indirect branch instructions and cannot prevent all forms of vulnerability exploitation. We also classify these techniques based on their security, robustness, and implementation complexity. In this paper, we assess the effectiveness of 14 CFI techniques against the most popular exploitation techniques, including code reuse attacks, return-to-user, return-to-libc, and replay attacks. Control-flow Integrity (CFI) is a large family of techniques that aims to eradicate memory error exploitation by ensuring that the instruction pointer (IP) of a running process cannot be controlled by a malicious attacker. Consequently, control-flow integrity has received significant attention in the research community, and software developers to combat control code execution attacks in the presence of type of faults. Despite the intense efforts to prevent programmers from writing code with memory errors, memory corruption vulnerabilities are still a major security threat.
