Security Vulnerabilities in the Java Runtime Environment may allow Same Origin Policy to be Bypassed

1. Impact

Security vulnerabilities in the Java Runtime Environment may allow an untrusted applet that is loaded from a remote system to circumvent network access restrictions and establish socket connections to certain services running on machines other than the one that the applet was downloaded from. This may allow the untrusted remote applet the ability to exploit any security vulnerabilities existing in the services it has connected to.

Sun acknowledges with thanks, Gregory Fleischer for bringing these issues 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
• SDK and JRE 1.3.x_22 and earlier

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"
3. 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:


The above example 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 that the above issue has been exploited.

4. Workaround

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