Impact A vulnerability in the Java Runtime Environment Virtual Machine may allow an untrusted application or applet that is downloaded from a website to elevate its privileges. For example, the application or applet may grant itself permissions to read and write local files or execute local applications that are accessible to the user running the untrusted application or applet. Sun acknowledges with thanks, Fujitsu for bringing this issue to our attention. 2. Contributing Factors This issue can occur in the following releases for Windows, Solaris, and Linux: JDK and JRE 6 Update 6 and earlier JDK and JRE 5.0 Update 15 and earlier SDK and JRE 1.4.2_17 and earlier Note: SDK and JRE 1.3.x are not affected. To determine the default version of the JRE that Internet Explorer uses: Click "Tools" in the Menu Bar at the top of the browser Select "Sun Java Console" 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: Java(TM) Plug-in 1.5.0_11-b03 The example above 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 issue has been exploited. 4. Workaround There is no workaround for this issue. Please see the Resolution section below. 5.
