Nokia 6310i cellular phones (and possibly others like it) could be subject of a denial of service attack when invalid OBEX messages are sent to the phones’ protocol handler. This attack results in the phone resetting, terminating any current operations. No device pairing is required therefore anyone in range of the phone could initiate an attack.
