Stack buffer overflow bugs are caused when a program writes more data to a buffer

located on the stack than what is actually allocated for that buffer. Study the

following C code and draw program stack in foo$()$ with various inputs:

i$.$ before data is copied

ii$.$ "Security" is provided as command line argument

iii. AAAAAAAAAAAAAAAAAAAA $\backslash$ x$0$A $\backslash$ xAF x D$8\backslash$ x$77$ is provided as

command line argument.

iv$.$ What does $\backslash$ x OA $\backslash$ xAF $\backslash$ xD $8\backslash$ x$77$ indicates? What happens when EIP is

filled with this address?

#include

void foo $($char $*$bar$)$

char c$[16]$;

strcpy$($c$,$ bar$)$;

$\}$

int main $($int argc, char $**$argv$)$

$\{$

foo$($argv$[1])$;
