Security Vulnerabilities in the Java Runtime Environment Scripting Language Support

1. Impact

A vulnerability in the Java Runtime Environment relating to scripting language support may allow an untrusted applet or application to elevate its privileges. For example, an untrusted applet may grant itself permissions to read and write local files or execute local applications that are accessible to the user running the untrusted applet.

A second vulnerability in the Java Runtime Environment relating to scripting language support may allow an untrusted applet to access information from another applet.

2. Contributing Factors

These issues can occur in the following releases for Windows, Solaris, and Linux:

• JDK and JRE 6 Update 6 and earlier

Note: JDK and JRE 5.0, and SDK and JRE 1.4.x and 1.3.x are not affected.

To determine the default version of the JRE that Internet Explorer uses:

1. Click "Tools" in the Menu Bar at the top of the browser
2. Select "Sun Java Console"
3. The first two lines in the console displays the version of Java Plug-in and JRE that Internet Explorer uses.

To determine the default version of the JRE that Mozilla or Firefox browsers use, visit the URL "about:plugins".

The browser will display a page called "Installed plug-ins" which lists the version of the Java Plug-in, as in the following example:


The above example indicates the version of the JRE that the browser uses is 1.5.0_11.

3. Symptoms

There are no predictable symptoms that would indicate the above issues have been exploited.

4. Workaround

There are no workarounds for these issue. Please see the resolution section below.

5. Resolution

These issues are addressed in the following releases for Windows, Solaris, and Linux:

• JDK and JRE 6 Update 7 or later

JDK and JRE 6 Update 7 are available for download at the following links:



JRE 6 updates are available through the Java Update tool for Microsoft Windows users.

JDK 6 Update 7 for Solaris is available in the following patches:
