comment Why is it dangerous when an attacker can control the `n` parameter to `memcpy()`?
This is also essentially the implementation bug that led to the big Heartbleed bug. The attacker controlled a length parameter that wasn't checked in any way, allowing the attacker to make the server send back big chunks of memory potentially containing secret keys, confidential data, passwords, and so on.

comment Can you really change the password to a mac on reboot without knowing the old one?
@Magpie: To prevent quick access by someone who only has a second to gain access, or to prevent access by the technically incompetent. These things can be prevented with a BIOS or EFI passwords required on each boot, though, you know.
