"could have been"? What about the HFS+ exploit?

well it's a "real" issue but it's nothing compared to others that have a wide security impact as in every script kiddie can pwn a webserver :
1) outdated CMS with remote code execution (mostly PHP) 2) easy execution of any executable 3) ready to use exploit that works reliably as unprivileged user
The HFS+ vuln is not exploitable in that case. While it can be used for "physical" attacks like the USB key, it is not usable remotely.
_Thousands_ of servers have been compromised with that scenario :

In the late eighties/early nineties I seem to recall infected floppy disks were the main (or at least a very common) vector for virus transmission.
If people don't exchange data on usb keys as much as they used to on floppies, perhaps that wouldn't be as effective these days.

Supposedly Stuxnet was transmitted using a USB key.

Stuxnet used a vulnerability in the Windows shell (the so-called LNK vulnerability), not in the filesystem code.
As for floppies, viruses spread mostly by running infected executables, not using vulns.
