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(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 为 inf 文件路径。若成功会看到“任务成功结束”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 "%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)。
