Security Vulnerabilities in the Java Runtime Environment (JRE) JAX-WS and JAXB Packages may Allow Privileges to be Escalated

---

Security vulnerabilities in the Java Runtime Environment (JRE) JAX-WS and JAXB packages:

1. Impact

Security vulnerabilities in the JAX-WS and JAXB packages in the Java Runtime Environment (JRE) where internal classes can be accessed may allow an untrusted applet or application to escalate privileges. For example, an untrusted 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, Adam Gowdiak for bringing these issues to our attention.

2. Contributing Factors

These issues can occur in the following Java SE and Java SE for Business releases for Solaris, Windows and Linux:

• JDK and JRE 6 Update 10 or earlier
  

Note: JDK and JRE 5.0, and SDK and JRE 1.4.x and 1.3.x are not affected by this issue.

To determine the default version of the JRE that Internet Explorer uses:

1. Click "Tools" in the Menu Bar at the top of the browser
2. Select "Sun Java Console"

The first two lines in the console display 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 shown in the following example:

    Java(TM) Plug-in 1.5.0_11-b03

(Indicating that the JRE version the browser uses is 1.5.0_11)

3. Symptoms

There are no reliable symptoms that would indicate the described issues have been exploited.

4. Workaround

There is no workaround for this issue. Please see the Resolution section below.
