Question

What happens if an attacker's string is internally converted into Unicode before it reaches the vulnerable function?

a.

The attacker must feed the vulnerable program a sequence of ASCII characters that would become a workable shellcode once converted into Unicode.

b.

The attacker can bypass the buffer length check.

c.

The caller can supply a string that is too long for the target buffer.

d.

The vulnerable program becomes less vulnerable to overflow attacks.
