Blackberry PDF vulnerabilities fixed
If you have a Blackberry Enterprise Server running on your company's network, you'll want to be aware of a new advisory regarding a vulnerability that could possibly result in buffer overflow errors and arbitrary code execution on the system that hosts the Blackberry Attachment Service, if a smartphone user opens a specially crafted PDF file. RIM has released updates for the affected versions of BB Enterprise Server Express for Exchange, IBM Lotus Domino and Novell Groupwise.
You can also apply a workaround that will prevent the BBAS from processing PDF files by editing the file format extensions that can be opened by the service. You can find out more about both the updates and the workaound here:
