发布时间:1999-09-29
更新时间:2000-09-29
严重程度:
威胁程度:本地管理员权限
错误类型:输入验证错误
利用方式:服务器模式

受影响系统
WinNT
IE4.01 FOR WIN95,NT4.0;\NIE5.0 FOR WIN95/98/NT
详细描述
IEF随带的hhopen OLE控件(hhopen.ocx)中存在一个缓冲溢出漏洞,这个控件中被标明为'Safe for Scripting'.可被恶意者利用此控件来执行两进制代码

测试代码
HHOPEN: This control is a little more difficult to exploit, as the RET address is in the middle of the string, and once again there is no easy way to RET to our code, so I have RET'd to ExitProcess directly instead. In this case, OpenHelp is the vulnerable method, and the exploit is possible when the method is called with a valid help file, and a long Help Section
