A security vulnerability in the Java Runtime Environment Swing library may allow an untrusted applet to access data in other applets.

Sun acknowledges, with thanks, Tom Hawtin, for bringing this issue to our attention.

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

• JDK and JRE 5.0 Update 7 and earlier

Note: SDK and JRE 1.4.2_xx and earlier and 1.3.1_xx and earlier are not affected by this issue.

To determine the default version of the JRE on a system for Solaris and Linux, the following command can be run:

    % java -version

Note: The above command only determines the default version. Other versions may also be installed on the system.

To determine the default version of the JRE on a system for Windows:

1. Click "Start"
2. Select "Run"
3. Type "cmd" (starts a command-line)
4. At the prompt, type "java -version"

Note: The above command only determines the default version. Other versions may also be installed on the system.

There are no reliable symptoms that would indicate the described issue has been exploited.

There is no workaround. Please see the "Resolution" section below.
