Fwd: [cros-discuss] Hacking possibility? Real or not?

In the mailing-list about Chromium OS is some interesting discussion
about some attack vector using an USB plug-in with some Raspery system
behind to offer to the OS an USB keyboard and ethernet and at the end
take over the system. More of the discussion here
and the full technical description here:
As far as I can see, the same attack would be possible as well on
FreeBSD, maybe not so easy because the devd(8) must be configured and
the module for ethernet on USB cdce(4) must be loaded in advance.

Subject: [cros-discuss] Hacking possibility? Real or not?
Mike Frysinger and other Chromium OS experts -
This rather one-sided Microsoft video brings up some interesting claims.
I'll ignore the claim that Windows is more secure, but I wonder about what
really is possible with ChromeOS devices.
I'd like us to get ahead of any more fear mongering by having someone
knowledgeable examine the actual threat. This appears to be the exploit:
For a protected mode ChromeOS device, what are the actual vulnerabilities
I expect that a logged in device could be exposed to data theft if the user
(or someone else) plugged in a malicious device, but what about a
locked-screen or logged out device?
For logged in, unlocked devices, what mischief could be done?
Anyone care to be a truth-teller here?
