From their press release:
On December 14th, 2007, Ohio Secretary of State Jennifer Brunner released the results of a comprehensive review of her state’s electronic voting technology. The study, called Project EVEREST, examined electronic voting systems – touch-screen and optical scan – from Elections Systems and Software (ES&S), Hart InterCivic, and Premier Election Systems (formerly Diebold). As part of that study, three teams of security researchers, based at Pennsylvania State University (State College, PA), the University of Pennsylvania (Philadelphia, PA), and WebWise Security, Inc. (Santa Barbara, CA), conducted the security reviews. The reviews began in September, 2007 and concluded on December 7, 2007 with the delivery of the final report. The teams had access to voting machines and software source code from the three vendors, and performed source code analysis and security penetration testing with the aim of identifying security problems that might affect the integrity of elections that use the equipment.

The report is similar to those that Debra Bowen had commissioned in California. In short, the electronic voting machines all had extremely serious flaws.
