微軟通報：4種方法暫時屏蔽IE漏洞IE 最新7.0波及了微軟全線系統，目前暫時沒有補丁。微軟於近日發佈了一份安全通報，指導您如何暫時屏蔽此漏洞。
漏洞出在 OLEDB32.dll 這個文件上。所以我們的目的就是屏蔽這個文件。對此，微軟連出了4個殺手鑭：
1. SACL 法（僅適用於 Vista）
[Unicode]
Unicode=yes
[Version]
signature="$CHICAGO$"
Revision=1
[File Security]
"%ProgramFiles%\Common Files\System\Ole DB\oledb32.dll",2,"S ML;;NWNRNX;;;ME)"
將以上內容保存為 BlockAccess_x86.inf
然後在命令提示符裡執行 SecEdit /configure /db BlockAccess.sdb /cfg <inf file>
其中 <inf file> 為 inf 文件路徑。若成功會看到「任務成功結束」的提示。
2. 禁用 Row Position 功能法
HKEY_CLASSES_ROOT\CLSID\{2048EEE6-7FA2-11D0-9E6A-00A0C9138C29}
打開註冊表編輯器，將此鍵刪除即可。
3. 取消 DLL 註冊法
在命令提示符中輸入 Regsvr32.exe /u "%ProgramFiles%\Common Files\System\Ole DB\oledb32.dll"
即可
4. 權限設置法
在命令提示符中輸入 cacls "%ProgramFiles%\Common Files\System\Ole DB\oledb32.dll" /E /P everyone:N
Vista 系統則需要輸入3個命令：
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 everyoneF)
其中第一種方法影響最小（只影響 IE 對此 DLL 的訪問）。
