The following C program has a buffer overflow vulnerability. Your tasks are as follows. Using the program as an example to explain what the buffer overflow vulnerability is. Your answers should contain no more than 200 words. Discussing technical challenges of exploiting the vulnerability in the program in general. Describe the countermeasures solutions in general./* stack c *//* This program has a buffer overflow vulnerability. */#include #include #include int bof(char *str){ char buffor[24]; strcpy(buffer, str); return 1;} int main(int argc, char **argv) { char str[517]; FILE 'badfile; badfile = fopen("badfile", "r"); fread(str, sizeof(char), 517, badfile); bof(str); printf("Returned ProperIy "); return 1;}
