It studies the algorithms for dynamic checking of array bounds overflow based on program instrumentation, implements the algorithms based on the open source compiler Clang. The experi-mental results show that this method is feasible and efficient.%缓存区溢出能引起非常严重的安全问题,对网络和分布式系统...
_Atomic类型修饰符和 头文件 <stdatomic.h>,见 7.17 节。带边界检查(Bounds-checking)的函数接口,定义了新的安全的函数,例如 fopen_s(),strcat_s() 等等。更多参考 Annex K。改进的 Unicode 支持,新的头文件 <uchar.h> 等。实例代码: #include<stdio.h> #include<uchar.h> size_t UTF16StrLen(constchar...
int main() { int array[10]; array[10] = 0; return 0; } 在这段代码中,我们试图访问数组的第11个元素,但数组的大小只有10。这将导致未定义的行为。 我们可以使用Cppcheck来检查这段代码: cppcheck --enable=all array_out_of_bounds.cpp Cppcheck的输出可能类似下面这样: Checking array_out_of_bou...

c/c++语言具备一个不同于其他编程语言的的特性,即支持可变参数。 例如C库中的printf,scanf等函数,都支持输入数量不定的参数。printf函数原型为 int printf(const char *format, …); printf("hello world");///< 1个参数printf("%d", a);///< 2个参数printf("%d, %d", a, b);///< 3个参数 测...

We can lower overheads by not bounds checking pointer escapes. -lowfat-no-check-fields: OOB-errors due to (non-array) field access are less common than those caused by array/buffer overflows. We can lower overheads by only bounds checking array/buffer access....
cppcheck是静态的C/C++ 代码分析工具,用以检查内存泄漏,错配的内存分配和释放,缓冲区溢出等问题。支持eclipse插件。 Someof the checks that are supported include: Automatic variablechecking Bounds checkingfor array overruns Classeschecking. (e.g. unused functions, variable intialisation and memory duplication...
