Control-Flow Integrity (CFI) Bypass
Control-Flow Integrity (CFI) Bypass is a type of computer security vulnerability. It affects the way that programs are executed on a computer.
When a program is running, its code is broken down into smaller instructions. These instructions tell the computer what to do, like adding two numbers together or storing data in memory. The instructions are executed one after the other, in a specific order.
CFI is a security feature that helps ensure that the program’s instructions are executed in the correct order. This prevents attackers from changing the program’s behavior by manipulating its control flow.
However, attackers have found ways to bypass CFI. They use techniques like code injection and return-oriented programming to trick the program into executing their own instructions. This can be a serious security risk, as it allows attackers to take control of the program and potentially the entire system.
To protect against CFI bypasses, software developers need to carefully design their programs to resist these attacks. Special tools and techniques can be used to identify and fix vulnerabilities. And users need to keep their software up-to-date, to ensure that any security patches are applied promptly.
In short, CFI bypasses are a type of computer security vulnerability that allow attackers to manipulate the control flow of a program. But with the right precautions, developers and users can fight back against these threats.
