1. Impact
Two vulnerabilities in the Java Runtime Environment may independently 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.
2. Contributing Factors
These issues can occur in the following releases (for Windows, Solaris, and Linux):
- JDK and JRE 6 Update 1 and earlier
- JDK and JRE 5.0 Update 13 and earlier
Note: SDK and JRE 1.4.x and earlier are not affected by these issues.
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 that the version of the JRE the browser uses is 1.5.0_11.
3. Symptoms
There are no predictable symptoms that would indicate the described issues have been exploited.
4. Relief/Workaround
There is no workaround for these issues. Please see the Resolution section below.
4. Resolution
