1] What is Control Flow Guard and how does it work Control Flow Guard is a feature that makes it harder for exploits to execute arbitrary code through vulnerabilities such as buffer overflows. As we know, software vulnerabilities are often exploited by providing unlikely, unusual, or extreme da...
这个分支必须转移控制以退出guard语句出现的代码段。它可以用控制转移语句如return,break或continue做这件事,或者它调用了一个不返回的方法或函数,例如fatalError()。 相比于可以实现同样功能的if语句,按需使用guard语句会提升我们代码的可靠性。 它可以使你的代码连贯的被执行而不需要将它包在else块中,它可以使你处理...
Control Flow Guard (CFG) is a highly-optimized platform security feature that was created to combat memory corruption vulnerabilities. By placing tight restrictions on where an application can execute code from, it makes it much harder for exploits to execute arbitrary code through vulnerabilities such...
To run Windows Subsystem for Android™ you’ll need to turn on Control flow guard (if you have a Windows version with build 25266 or earlier). Note:You can find outwhich version of Windows operating system you're runningif you're not sure. In the search box on th...
Windows的CFI实现称为Control Flow Guard(CFG),因为实际的性能要求,不可能做到非常精确的CFI,因此,实际在windows上部署的CFI是粗粒度的、前向CFI。首先,粗粒度的CFI是:所有的有效跳转地址为一个全局的集合,即不精确的为每一个间接跳转指定一个有效跳转地址;其次,什么叫做前向CFI:只考略call,jump的直接跳转和间接跳...
如果你使用这种或类似的执行方法,你会遇到一个阻碍:Microsoft 的 Control Flow Guard (CFG)。 CFG是一种包含在Windows中的反利用技术(从Windows 8.1开始),它可以防止任意代码在程序中间接执行。这可以阻止尝试禁用数据执行保护 (DEP) 或将包含恶意代码的只读/只写缓冲区设置为可执行的攻击。
/guard:cf-RemarksThe /guard:cf option causes the compiler to analyze control flow for indirect call targets at compile time, and then to insert code to verify the targets at runtime. By default, /guard:cf is off and must be explicitly enabled. To explicitly disable this option, use /guar...

As part of our ongoing efforts towards safer systems programming, we’re pleased to announce that Windows Control Flow Guard (CFG) support is now available in the Clang C/C++ compiler and Rust. What is Control Flow Guard? CFG is a platform security technology designed to enforce control ...
