Bug Id
6571539

Date of Resolved Release
22-OCT-2007

Impact

A vulnerability in the Virtual Machine of the Java Runtime Environment may allow an untrusted applet to elevate its privileges. For example, an 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.

Sun acknowledges with thanks, Azul Systems, Inc., for bringing this issue to our attention.

Contributing Factors

This issue can occur in the following releases (for Windows, Solaris, and Linux):

• JDK and JRE 6 Update 2 and earlier
• JDK and JRE 5.0 Update 12 and earlier
• SDK and JRE 1.4.2_15 and earlier
• SDK and JRE 1.3.1_20 and earlier

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 display 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:

Java(TM) Plug-in 1.5.0_11-b03

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

Symptoms

There are no predictable symptoms that would indicate the issue described is being exploited.
