ASan,即Address Sanitizer,是一个由Google开发的适用于c/c++的动态内存错误检测器,它由一个编译器检测模块(LLVM pass)和一个替换malloc函数的运行时库组成,在性能及检测内存错误方面都优于Valgrind。 -fsanitize=address 悬空指针(时间问题) 缓冲区溢出(空间问题) heap-buffer-overflow stack-
Global Buffer Overflow：全局缓冲区溢出，与堆溢出具有相似之处。Use After Return：在函数返回后使用其返回的内存，这通常涉及返回一个临时变量的指针或引用。在初步了解了ASan的工作原理后，我们可以尝试通过一个具体实例来实践其使用。使用ASan的主要流程包括以下几个步骤：编写测试程序。在编译时添加相关参数。编译并...

AddressSanitizer是Google用于检测内存各种buffer overflow(Heap buffer overflow, Stack buffer overflow, Global buffer overflow)的一个非常有用的工具。该工具是一个LLVM的Pass,现已集成至llvm中,要是用它可以通过-fsanitizer=address选项使用它。AddressSanitizer的源码位于/lib/Transforms/Instrumentation/AddressSanitizer.cpp...

AddressSanitizer can't detect some global buffer overflow! Even if the mistake or code bugs is so obvious。 for example,this code bellow, guess what you will get, ... U08 IP[10]; U08 IP1[10]; int main() { memset(IP1,0x3A,10); memcpy(IP,"123456789021111111111",17); IP[15] = ...
