Last Friday (6 June 2014), the FAA published a proposal for additional requirements that would make it less likely that someone could hack into critical electronic systems on some 737 models. The language is a bit dense, but the implication is that several models of the 737 (the 737-700, -700C, -800, -900ER, -7, -8, and -9 series) have an unusual design feature that allows access to the airplane's critical systems and data network by way of the passengers service computer systems.

It is not at all clear that this is a current danger, or if a 737 has already been hacked. For more details, you can review the Federal Register item that discusses this issue (Federal Register Vol. 79, No. 109, pages 32642-3), and for further details you can find out more in the docket folder for Docket FAA-2014-0302

What's the problem?

According to the FAA, the applicable airworthiness regulations do not contain adequate or appropriate safety standards to prevent inappropriate access to critical information systems. The special conditions that the FAA wants to add to the regulations contain additional safety standards that would presumably establish a level of safety equivalent to existing airworthiness standards.
