Buffer and Integer Overflow Vulnerabilities in the Java Runtime Environment With Processing Audio and Image Files May Allow Privileges to be Escalated

---

Buffer and integer overflow vulnerabilities in the Java Runtime Environment:

1. Impact

Multiple buffer and integer overflow vulnerabilities in the Java Runtime Environment with processing audio and image files may allow an untrusted applet or Java Web Start 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, the following researchers for bringing these issues to our attention:

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

• http://java.com/en/download/installed.jsp?detect=jre&try=1

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:

    Java(TM) Platform SE 6 U15

In this example, the version of the JRE that the browser uses is 6 Update 15.
