Java 2 Platform, Standard Edition

PX7GT4I Internal ID use only.

A vulnerability in the font parsing code in 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, John Heasman of NGSSoftware, for bringing this issue to our attention.

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

• JDK and JRE 5.0 Update 9 and earlier
• SDK and JRE 1.4.2_14 and earlier

Note: JDK and JRE 6 and SDK and JRE 1.3.1_xx 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 show the described issue has been exploited.

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

This issue is addressed in the following releases (for Solaris, Linux, and Windows):

• JDK and JRE 5.0 Update 10 or later
• SDK and JRE 1.4.2_15 or later
