Microsoft 安全通报：4 种方法暂时屏蔽 IE 最新 0day

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）
[Unicode]
Unicode=yes
[Version]
signature="$CHICAGO$"
Revision=1
[File Security]
"%ProgramFiles%Common FilesSystemOle DBoledb32.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“任务成功结束”的提示。

2. 禁用 Row Position 功能法

关于漏洞细节可查看：

ms08069利用代码exploit 网马

HKEY_CLASSES_ROOTCLSID{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 FilesSystemOle DBoledb32.dll"
即可

4. 权限设置法

在命令提示符中输入 cacls "%ProgramFiles%Common FilesSystemOle DBoledb32.dll" /E /P everyone:N

Vista 系统则需要输入3个命令：

takeown /f "%ProgramFiles%Common FilesSystemOle DBoledb32.dll"
icacls "%ProgramFiles%Common FilesSystemOle DBoledb32.dll" /save %TEMP%oledb32.32.dll.TXT
icacls "%ProgramFiles%Common FilesSystemOle DBoledb32.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）。
