Category Security Release Phase Resolved 6646860, 6724331, 6706490, 6798948, 6782871 Product Sun Java Standard Edition (Java SE) Date of Resolved Release 24-Mar-2009 Multiple Security Vulnerabilities in Java Plug-in May Allow Privileges to be Escalated 1. Impact CR 6646860: A security vulnerability in the Java Plug-in with deserializing applets may allow an untrusted applet 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. CR 6724331: The Java Plug-in allows Javascript code that is loaded from the localhost to connect to any port on the system. This may be leveraged together with XSS vulnerabilities in a blended attack to illegally access other applications listening on ports other than the one where the Javascript code was served from. CR 6706490: The Java Plug-in allows a trusted applet to be launched on an earlier version of the Java Runtime Environment (JRE) provided the user that downloaded the applet allows it to run on the requested release. A vulnerability allows Javascript code that is present in the same web page as the applet to exploit known vulnerabilities of the requested JRE. CR 6798948: A security vulnerability in the Java Plug-in with parsing crossdomain.xml files may allow an untrusted applet to connect to any site that provides a crossdomain.xml file instead of sites that allow the domain that the applet is running on. CR 6782871: A security vulnerability in the Java Plug-in may allow a signed applet to obscure the contents of the security dialog and thereby trick a user into trusting the applet. Sun acknowledges with thanks: Gregory Fleischer (for CR 6798948) and Michael Schierl (for CR 6782871). 2. Contributing Factors CR 6646860 can occur in the following Java SE and Java SE for Business releases for Windows, Solaris, and Linux:
CR 6706490 and 6798948 can occur in the following Java SE and Java SE for Business releases for Windows, Solaris, and Linux:
CR 6782871 can occur in the following Java SE and Java SE for Business releases for Windows, Solaris, and Linux:
To determine the default version of the JRE that Internet Explorer uses, visit the URL: 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: Java(TM) Platform SE 6 U11
The above example indicates the version of the JRE that the browser uses is version 6 Update 11. 3. Symptoms There are no reliable symptoms that would indicate the described issues have been exploited. 4. Workaround There are no workarounds for these issues. Please see "Resolution" section below. 5. Resolution CR 6646860 is addressed in the following Java SE and Java SE for Business releases for Windows, Solaris, and Linux:
