Two Security Vulnerabilities in the Java Runtime Environment Virtual Machine

1. Impact

Two security vulnerabilities in the Java Runtime Environment Virtual Machine 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.

Sun acknowledges with thanks, Fujitsu for bringing the first issue to our attention.

2. Contributing Factors

The first issue can occur in the following releases (for Windows, Solaris,and Linux):

• JDK and JRE 6 Update 4 and earlier
• JDK and JRE 5.0 Update 14 and earlier
• SDK and JRE 1.4.2_16 and earlier

Note: SDK and JRE 1.3.x is not affected by this issue.

The second issue can occur in the following releases (for Windows, Solaris, and Linux):

• JDK and JRE 5.0 Update 13 and earlier
• SDK and JRE 1.4.2_16 and earlier

Note: JDK and JRE 6, and SDK and JRE 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 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 such as the following:


The above indicates the version of the JRE the browser uses is 1.5.0_11.

3. Symptoms

There are no predictable symptoms that would indicate that the above issues are being exploited.

4. Workaround

There is no workaround for these issues. Please see the Resolution section below.

5. Resolution

The first issue is addressed in the following releases (for Windows, Solaris, and Linux):

• JDK and JRE 6 Update 5 or later

The second issue is addressed in the following releases (for Windows, Solaris, and Linux):

• JDK and JRE 5.0 Update 14 or later
• SDK and JRE 1.4.2_17 or later

Note: Sun had announced in September 2007 that we will be synchronizing the release of fixes for security vulnerabilities starting in 2008. This issue was addressed in 5.0 Update 14 prior to the announcement and is addressed in 1.4.2_17 as part of the first set of synchronized updates.
