Compile:
gcc win-tcpip-dos.c -o wintcpipdos
Info:
Published: 14.06.2006
Source: ANDREYMINAEV
Type: remote
Level: 9/10
Buffer overflow on ICMP packets with
Loose Source and Record Route IP options.
Short message translation: There are DoS
conditions in Windows 2000 built-in NAT
server. Tested configuration: Windows 2000
English Standard/Advanced Service Pack 4
+ Update Rollup 1 for Service Pack 4 with
NAT server enabled. While routing packets
with options "Loose Source and Record Route"
defined by RFC 791 through server, Windows
crashes to BSOD with error in tcpip.sys or
ntoskrnl.exe, or system hangs or system
began instable work. It doesn't metter if
packets are from internal or external
networks. Use attached script to test
vulnerability. On Windows 2003 problem
doesn't present. It's also likely same
problem to present in Windows 2000 +
ISA 2000. Code execution is potentially possible.
