Hello, A friend and I were playing around sending SMS messages the other day between a Nokia 3390 and his Handspring VisorPhone/Visor Prism combo. Sending text messages seemed to work just fine. However, on the Nokia, there is an option of sending SMS images. Apparently, they are fairly large as they take a while to send. The VisorPhone appears capable of accepting these messages, but the VisorPhone database inside the PalmOS isn't (at least, the version he had loaded). Whenever it transfers the image into the VisorPhone database, it fatally crashes PalmOS and leaves the VisorPhone database corrupted. In order to recover, he had to reboot the Visor (which disconnects the call) and then attempt to delete the phone database (which includes SMS messages). This has the affect of deleting all VisorPhone information (call logs, SMS archived messages, custom messages, etc). I doubt it touched the standard PalmOS contacts database. I tested it twice with the same results. So, if you're into crashing VisorPhones, try sending an SMS image from a Nokia. :) This vulnerability may also exist when sending custom ringtones and other Nokia specific SMS messages. I don't know the exact version of the VisorPhone software/hardware nor the exact version of PalmOS running on the Visor Prism, but it's likely to work with what's shipping today. I also haven't tested on anything other than the Visor as I don't have access, but other PalmOS based phones may be vulnerable. ===== -- Brian Wright <commorancyat_private> __________________________________________________ Do You Yahoo!?
