漏洞出在 OLEDB32.dll 这个文件上。所以我们的目的就是屏蔽这个文件。对此,微软连出了4个杀手锏: 1. SACL 法(仅适用于 Vista) 新建记事本,复制下列内容: [Unicode] Unicode=yes [Version] signature="$CHICAGO$" Revision=1 [File Security] "%ProgramFiles%\Common Files\System\Ole DB\oledb32.dll",2,"S:(ML;;NWNRNX;;;ME)" 保存为 BlockAccess_x86.inf 然后在命令提示符里执行 SecEdit /configure /db BlockAccess.sdb /cfg 其中 2. 禁用 Row Position 功能法 HKEY_CLASSES_ROOT\CLSID\{2048EEE6-7FA2-11D0-9E6A-00A0C9138C29} 打开注册表编辑器,将此键删除即可。 3. 取消 DLL 注册法 在命令提示符中输入 Regsvr32.exe /u "%ProgramFiles%\Common Files\System\Ole DB\oledb32.dll" 即可 4. 权限设置法 在命令提示符中输入 cacls "%ProgramFiles%\Common Files\System\Ole DB\oledb32.dll" /E /P everyone:N Vista 系统则需要输入3个命令: takeown /f "%ProgramFiles%\Common Files\System\Ole DB\oledb32.dll" icacls "%ProgramFiles%\Common Files\System\Ole DB\oledb32.dll" /save %TEMP%\oledb32.32.dll.TXT icacls "%ProgramFiles%\Common Files\System\Ole DB\oledb32.dll" /deny everyone:(F) 其中第一种方法影响最小(只影响 IE 对此 DLL 的访问)。 附:此漏洞影响的系统、软件列表 Windows Internet Explorer 7 Windows Internet Explorer 7 for Windows XP Windows Internet Explorer 7 for Windows Server 2003 Windows Internet Explorer 7 for Windows Server 2003 IA64 Windows Internet Explorer 7 in Windows Vista Windows Internet Explorer 8 Beta Microsoft Internet Explorer 6.0 Service Pack 2 Microsoft Internet Explorer 6.0 Service Pack 1 Microsoft Internet Explorer 6.0 Microsoft Internet Explorer 5.01 Service Pack 4 Windows Server 2008 Datacenter without Hyper-V Windows Server 2008 Enterprise without Hyper-V Windows Server 2008 for Itanium-Based Systems Windows Server 2008 Standard without Hyper-V Windows Server 2008 Datacenter Windows Server 2008 Enterprise Windows Server 2008 Standard Windows Web Server 2008 Windows Vista Service Pack 1, when used with: Windows Vista Business Windows Vista Enterprise Windows Vista Home Basic Windows Vista Home Premium Windows Vista Starter Windows Vista Ultimate Windows Vista Enterprise 64-bit Edition Windows Vista Home Basic 64-bit Edition Windows Vista Home Premium 64-bit Edition Windows Vista Ultimate 64-bit Edition Windows Vista Business 64-bit Edition Microsoft Windows Server 2003 Service Pack 1, when used with: Microsoft Windows Server 2003, Standard Edition (32-bit x86) Microsoft Windows Server 2003, Enterprise Edition (32-bit x86) Microsoft Windows Server 2003, Datacenter Edition (32-bit x86) Microsoft Windows Server 2003, Web Edition Microsoft Windows Server 2003, Datacenter Edition for Itanium-Based Systems Microsoft Windows Server 2003, Enterprise Edition for Itanium-based Systems Microsoft Windows Server 2003, Datacenter x64 Edition Microsoft Windows Server 2003, Enterprise x64 Edition Microsoft Windows Server 2003, Standard x64 Edition Microsoft Windows XP Professional x64 Edition Microsoft Windows Server 2003 Service Pack 2, when used with: Microsoft Windows Server 2003, Standard Edition (32-bit x86) Microsoft Windows Server 2003, Enterprise Edition (32-bit x86) Microsoft Windows Server 2003, Datacenter Edition (32-bit x86) Microsoft Windows Server 2003, Web Edition Microsoft Windows Server 2003, Datacenter x64 Edition Microsoft Windows Server 2003, Enterprise x64 Edition Microsoft Windows Server 2003, Standard x64 Edition Microsoft Windows XP Professional x64 Edition Microsoft Windows Server 2003, Datacenter Edition for Itanium-Based Systems Microsoft Windows Server 2003, Enterprise Edition for Itanium-based Systems Microsoft Windows XP Service Pack 2, when used with: Microsoft Windows XP Home Edition Microsoft Windows XP Professional Microsoft Windows XP Service Pack 3, when used with: Microsoft Windows XP Home Edition Microsoft Windows XP Professional 对于非 x86 系统请参考微软安全通报自行操作。 【责任编辑 王凡】 |
