Researchers at Columbia University say millions of HP LaserJet printers are vulnerable to infected print jobs. Ang Cui and Salvatore Stolfo demonstrated an exploit whereby the duo could send virus-laden print jobs to a recently purchased LaserJet to overwrite the firmware and take control of the printer. HP has confirmed the exploit but claims the risk is not as great as the original MSNBC story characterized it, and has promised a firmware fix.
