An issue in the BlackBerry Device Software where a browser dialog box is not properly dismissed has been corrected in current releases of BlackBerry Device Software.

The browser displays the application name or vendor string on the download screen (this appears as several lines). The long application name indicates that there may be problems with the JAD file and caution should be exercised when downloading the application.

Complete the resolution actions documented in this advisory.

This article is in reference to US-CERT Advisory VU#829400.


You are running BlackBerry Device Software prior to version 4.0.2. You go to a web site and attempt to download a Java® Application Descriptor (JAD) file to your BlackBerry smartphone. If the JAD file is formatted to contain a long application name and vendor string (i.e., 256 or more characters), the browser appears to stop responding.

This does not affect other applications on the BlackBerry Device Software.


Install BlackBerry Device Software 4.0.2 or later. To obtain the most recent version of BlackBerry Device Software, contact your wireless service provider. To determine the BlackBerry Device Software version, click OptionsAbout.

RIM thanks FX of Phenoelit  for reporting this issue to RIM, and working with RIM to protect its customers.
