Java 2 Platform, Standard Edition
Date of Workaround Release
Date of Resolved Release
A vulnerability in the Java Runtime Environment may allow an untrusted Java Web Start application or Java applet to move or copy arbitrary files on the system that the application or applet runs on, by requesting the user of the application or applet to drag a file from the application or applet window to a desktop application that has permissions to accept and write files on the system. To exploit this vulnerability, the application or applet has to successfully persuade the user to drag and drop the file.
This issue can occur in the following releases (for Windows, Solaris, and Linux):
To determine the default version of the 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:
Java(TM) Plug-in 1.5.0_11-b03
The above example indicates that the version of the JRE that the browser uses is 1.5.0_11.
There are no predictable symptoms that would indicate that the above issue is being exploited.
To reduce the likelihood of executing untrusted applications which may allow this issue to be exploited, Java Web Start applications may be disabled temporarily (until the updates or patches have been installed) as follows:
For Internet Explorer (Windows):
Note 1: On Microsoft Windows, applications may also be launched from the desktop icon or Start Menu if a shortcut was previously created for an application. Unknown applications should not be launched through the desktop icon or the Start Menu. Shortcuts can be removed by using the Java Web Start Application Manager through the "Application/Remove Shortcut" menu item. For more information, see:
Note 2: It is also possible to launch applications through the command line in Windows, Solaris, and Linux. Unknown applications should not be launched through the command line. Sites may consider renaming the Java Web Start launcher ("javaws.exe" for Windows and "javaws" for Solaris and Linux) to prevent Java Web Start from launching.
The launcher can be found at:
JDK and JRE 6:
JDK and JRE 5:
SDK and JRE 1.4.2:
Solaris (if installed using pkg):
Linux (if installed using rpm):
This issue is addressed in the following releases (for Windows, Solaris, and Linux):
This issue is addressed in the following release (for Solaris 8 and Windows):
JDK and JRE 6 Update 3 is available for download at the following links:
JDK 6 Update 3 for Solaris is available in the following patches:
JDK and JRE 5.0 Update 13 is available for download at the following link:
JDK 5.0 Update 13 for Solaris is available in the following patches:
SDK and JRE 1.4.2 is available for download at:
SDK and JRE 1.3.1 for Solaris 8 is available for download at:
SDK and JRE 1.3.1 have completed the Sun End of Life (EOL) process and is only supported for customers with Solaris 8 and Vintage Support Offering support contracts (see http://java.sun.com/j2se/1.3/download.html). Sun strongly recommends that users upgrade to the latest releases.
Note: When installing a new version of the product from a source other than a Solaris patch, it is recommended that the old affected versions be removed from your system. To remove old affected versions on the Windows platform please see:
