Microsoft 安全通報:4 種方法暫時防禦 IE 最新 0day

Internet Explorer 最新 0day 波及了微軟全線系統,目前暫時沒有修補檔。微軟於近日發佈了一份安全通報,指導您如何暫時避免此漏洞。由於漏洞出在「OLEDB32.dll」這個檔案上。所以我們的目的就是隔離這個檔案。對此,微軟連出了4種殺手鐧。

第一式: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)"

將以上內容儲存為「BlockAccess_x86.inf」,然後在命令提示字元裡執行「SecEdit/configure/db BlockAccess.sdb/cfg "inf file"」,其中"inf file"整個字串為 inf 檔案路徑。如果成功會看到「The task has completed successfully.」的提示,或查看「%windir%\Security\Logs\」目錄下的「Scesrv.log」記錄檔。

第二式:禁用 Row Position 功能法
「HKEY_CLASSES_ROOT\CLSID\{2048EEE6-7FA2-11D0-9E6A-00A0C9138C29}」,打開註冊表編輯器,將此鍵值刪除即可。

第三式:取消 DLL 註冊法
在命令提示符中輸入「Regsvr32.exe/u "Program Files\Common Files\System\Ole DB\oledb32.dll"」即可。

第四式:權限設定法
在命令提示字元中輸入「cacls "Program Files\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 "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) 」。

其中第一式影響最小,僅會影響 IE 對此 DLL 的啟用。
