I’m not sure how recent this is but Daniel Cid brought it to my attention.

Description: Microsoft Windows Vista (SP0) dumps interfaces when it receives this ARP packet. This DoS is useful for an internet cafe, wireless venue, or legitimate local attack. The victim will need to manually refresh their network interface. OK, sure it’s a dumb local attack, but why does Vista disable iface!?!??

The python code can be found here: http://www.milw0rm.com/exploits/3926

Try it out, it’s kind of…well…disturbing.
