stringzz
Use a format string to pwn this program and get a flag. Its also found in /problems/stringzz_2_a90e0d8339487632cecbad2e459c71c4 on the shell server. Source.
- 1.Even though the flag is loaded onto the heap, there’s still a pointer to it located on the stack:
char * buf = malloc(sizeof(char)*FLAG_BUFFER);
FILE *f = fopen("flag.txt","r");
fgets(buf,FLAG_BUFFER,f);
