Read the following code for a login system. Suppose the variable password and continue are pushed to the stack one by one. If you are an attacker, $1)$ write a password you will input to achieve a heap$-$based buffer overflow attack. $2)$ What is the fundamental problem that generates this vulnerability? int main $($int arg, char $*$argvil$)($ char continue $=\text{'}$n$\text{'}$; char password $[8]$; stropy $($password$,$ argv$[1])$; if $($strcmp $($password$,$ "COSC$4363")==0)($ continue $=\text{'}$y$\text{'}$; $)$ if $($continue$=\text{'}$y$\text{'})(*$login$()$;$\}\}$
