A class action lawsuit filed in U.S. District Court in California against Hewlett-Packard could have wide ranging implications for software makers. The suit was filed on December 1 on behalf of David Goldblatt, a New York resident who purchased two HP printers. It alleges that HP does not require its printers to accept only digitally signed updates, opening the devices to malicious, remote updates that could give hackers control over the devices, which can be used to steal information, attack other computers on the same network as the printer.
