Overview

The Outlook 98 Java Permissions Security Update protects you from a vulnerability in Microsoft Outlook® 98 that allows HTML e-mail messages to launch an instance of your Internet browser with security settings at a decreased level. Because malicious Java code could potentially execute from HTML e-mail, this update will set "Java permissions" for the Microsoft Virtual Machine to "Disable Java" for the Restricted Sites zone. This will not impact the way your computer interacts with Java in normal Web browsing.


Note   Before you install the Java Permissions Security Update, you must install the Outlook 98 E-mail Security Update.


Note   To install this update, you must have administrator-level privileges on the machine you are using. If you are not an administrator, you can manually update the security settings in your browser by using the procedure below. If you do not have the Microsoft VM heading then the manual procedure and update do not need to be applied to your computer.

Change security settings in Microsoft Internet Explorer 5 or later

1. On the Tools menu, click Internet Options.
2. On the Security tab, click Restricted sites, and then click Custom Level....
3. Scroll down to the Microsoft VM heading, and select Disable Java under the Java permissions heading.
4. Click OK to change the custom setting, and click OK again to apply your new security setting and exit the Internet Options dialog box.

If a user manually modifies the security settings, the settings they have manually chosen will be honored for their current session and for their future logons on that machine. The settings established by this update will be applied for each subsequent user.
