IE 最新 0day 波及了微软全线系统，目前暂时没有补丁。微软于近日发布了一份安全通报，指导您如何暂时屏蔽此漏洞。
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
[Unicode]
Unicode=yes
[Version]
signature=$CHICAGO$
Revision=1
[File Security]
%ProgramFiles%\Common Files\System\Ole DB\oledb32.dll,2,S:(ML;;NWNRNX;;;ME)
将以上内容保存为 BlockAccess_x86.inf
然后在命令提示符里执行 SecEdit/configure/db BlockAccess.sdb/cfg <inf file>
其中 <inf file> 为 inf 文件路径。若成功会看到“操作成功完成”的提示。
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 Program Files\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 Program Files\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 Program Files\Common Files\System\Ole DB\oledb32.dll
icacls Program Files\Common Files\System\Ole DB\oledb32.dll/save %TEMP%\oledb32.32.dll.TXT
icacls Program Files\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）。
