(Critical Issue) Please carry out the countermeasure for the zero-day attack.

Certain period is needed for coping with newly-discovered software security vulnerability.
Zero-day attack is to attack during the period unpatched by the software developer from the newly-discovered security vulnerability.

Therefore, it is  very critical security issue.

Microsoft co. reported about the zero-day attack for Internet Explorer (all versions: 6, 7, 8, 9, 10, 11)

*Especially, if the user  logs in as the administrator, the attack may be able to get all permission of the user’s PC.

Tentatively stop the use of Internet Explorer

If you don’t need to use Internet Explorer, you had better use the other web browser, such as Firefox, Google Chrome and so on as much as possible.

Confirm “Windows Update” (May 2, 2014)

On May 2, 2014, Microsoft published the fixed patch (MS14-021).  According to some news, the patch will be automatically installed to Windows OS, but we strongly recommend the status check of the latest patches by accessing http://update.microsoft.com/microsoftupdate during several days.

How to check the installed patch

Basically, Microsoft Update  is available in the PC to which the Office program was installed.
However, in case of special case (*1), please upgrade the setting to Microsoft Update (*2).

*1  A case is the PC to which Office hasn’t installed.

*2 Upgrade to Microsoft Update

At least, Please carry out the following avoidance measures for preventing from various unknown  threats.

In case of using Internet Explorer for the special reason

Kyoto University provides the authentication IC service for accessing to the various local service of Kyoto University. For using this service, basically, Internet Explorer is required. Of course, Firefox can use, but the complex setting is required.

About the service, please contact here.

Therefore, Please carry out the countermeasures by seeing the following web page.

The Office would like to explain the following two major countermeasures.

* Please remember that these countermeasures are tentative avoidance measure. 
Even if these countermeasures are carried out, the security issue exists yet until the security patch is published by Microsoft co.

1. How to install EMET

EMET = Enhanced Mitigation Experience Toolkit

2. How to Unregister "VGX.DLL"

 The influence is not to display the web page constructed by VML (Vector Markup Language).
We recommend to use the other web browser if you need to display the VML page.

WindowsXP

The support for WindowsXP was finished, so radical countermeasure does not exist.
By the avoidance measures, the security issue can be tentatively avoided, but  we strongly recommend the OS upgrade or PC replacement.
