        赛门铁客防火墙D.o.s攻击代码

名称：HOD-symantec-firewall-DoS-expl.c:
版本：Version 0.1 coded by houseofdabus
翻译：luoluo
漏洞发现：www.eEye.com
漏洞描述：http://www.eeye.com/html/Research/Advisories/AD20040512B.html

* -------------------------------------------------------------------
* 程序测试:
* - Symantec Norton Personal Firewall 2004


* 受影响产品:
* - Symantec Norton Internet Security 2002
* - Symantec Norton Internet Security 2003
* - Symantec Norton Internet Security 2004
* - Symantec Norton Internet Security Professional 2002
* - Symantec Norton Internet Security Professional 2003
* - Symantec Norton Internet Security Professional 2004
* - Symantec Norton Personal Firewall 2002
* - Symantec Norton Personal Firewall 2003
* - Symantec Norton Personal Firewall 2004
* - Symantec Client Firewall 5.01, 5.1.1
* - Symantec Client Security 1.0, 1.1, 2.0(SCF 7.1)
* - Symantec Norton AntiSpam 2004

* -------------------------------------------------------------------
* 说明:
eEye Digital Security 现已发现在 Symantec 防火墙系列产品中存在的第二个安全漏洞，该漏洞可以被远程探测，并被利用来针对受影响系统进行拒绝服务攻击. 通过发送单个恶意 DNS (UDP 端口 53)响应包给存在漏洞的主机, 攻击者可以使 Symantec DNS 响应确认代码在内核中进入死循环，直至系统崩溃。受攻击主机只能通过物理重启，才能恢复运行.

* -------------------------------------------------------------------
* 编译:
* Win32/VC++ : cl -o HOD-sym-DoS-expl HOD-sym-DoS-expl.c ws2_32.lib
* Win32/cygwin: gcc -o HOD-sym-DoS-expl HOD-sym-DoS-expl.c -lws2_32.lib
* Linux : gcc -o HOD-sym-DoS-expl HOD-sym-DoS-expl.c -Wall

* -------------------------------------------------------------------
* 命令行参数/说明:

* HOD-symantec-firewall-DoS-expl [-fi:str] [-tp:int] [-ti:str] [-n:int]

* -fi:IP From (sender) IP address
* -tp:int To (recipient) port number
* -ti:IP To (recipient) IP address
* -n:int Number of times to send message
