受影响系统：
Honeywell Ademco ATNBaseLoader100 ActiveX 5.4.0.6描述：
BUGTRAQ ID: 24172
Honeywell是一家著名的美国安防产品公司，Ademco是其防盗报警产品之一。
Ademco产品所使用的ATNBaseLoader100模块（ATNBaseLoader100.dll）ActiveX控件处理畸形参数时存在缓冲区溢出漏洞，远程攻击者可能利用此漏洞控制用户机器。
ATNBaseLoader100模块（ATNBaseLoader100.dll）ActiveX控件在处理Send485CMD()、SetLoginID()和AddSite()方式时存在栈溢出漏洞。如果用户受骗访问了恶意站点并向这些方式传送了超长参数的话，就可以触发这个溢出，导致执行任意指令。
