3.3 全局缓冲区溢出(Global Buffer Overflow) 案例描述:检测对全局变量边界以外的内存写入操作。 参考代码如下: #include <stdio.h> #include <string.h> char globalBuffer[5]; int main() { strcpy(globalBuffer, "Hello, World!"); printf("Global Buffer contents: %s\n", globalBuffer); return 0; }...
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] = 1...
