New Scientist is reporting what appears to a serious security flaw in the bluetooth protocol. The flaw allows a hacker to force device pairing at will, and key discovery apparently takes less than .06 seconds on a Pentium IV.
This is not the security flaw found in February.

Update: the risk may well be overblown in the New Scientist article. See my follow-up post here.
