                       Windows Internet Name Service (WINS)
                           Remote Heap Buffer Overflow
                       ------------------------------------
                       ------------------------------------

Advisory credits:
----------------

		Nicolas Waisman of Immunity Inc. (www.immunitysec.com)

Advisory link:
----------------

		immunitysec.com/downloads/instantanea.pdf

Fix:
----------------

		support.microsoft.com/kb/870763 (MS04-045)

Exploit method:
----------------

		PEB (RtlEnterCriticalSection)

Tested Working:
----------------

		Win2k SP4          Server ENGLISH (should be all langages, not sure)
		Win2k SP4 Advanced Server ENGLISH (should be all langages, not sure)
		                     (KB870763 removed!)

Note:
----------------

		A HAT-SQUAD view on this hole; exploitable and remaining critic for Windows 2000.
		May need update for Windows 2003 due to the different
		structure of wins.exe in it but the bug remain exploitable
		with no KB870763 of course....
		If you look closely at my code , you will notice two overwrites,
		this is the difference between Server <=> Advanced Server, with an
		el8 pad, repair, you catch them both.

Greetings:
----------------

		All guys at hat-squad and metasploit
		also #n3ws at EFnet, useful to keep an eye on security.. (50 rsslinks)
		and thanx you leku.

Update:
----------------

		v0.2: runtime error fixed
		v0.3: hardcoded repair, much decent and stable
		v0.3: FreeBSD compilation fixed: gcc 101_WINS.cpp -o 101_WINS
