These issues are addressed in the following versions of the Sun Java Runtime environment: * JDK and JRE 6 Update 7 * JDK and JRE 5.0 Update 16 * SDK and JRE 1.4.2_18 * SDK and JRE 1.3.1_23
If you install the latest version of Java, older versions may remain installed on your computer. If you do not need these older versions, you can remove them by following Sun's instructions.
Disable Java in your web browser, as described in the Securing Your Web Browser document. While this does not fix the underlying vulnerabilities, it does block a common attack vector.
