CWmike (1292728) writes "Microsoft uncovered more than 1,800 bugs in Office 2010 by tapping into the unused computing horsepower of idling PCs, a company security engineer said on Wednesday. Office developers found the bugs by running millions of 'fuzzing' tests, a practice employed by both software developers and security researchers, that searches for flaws by inserting data into file format parsers to see where programs fail by crashing. 'We found and fixed about 1,800 bugs in Office 2010's code," said Tom Gallagher, senior security test lead with Microsoft's Trustworthy Computing group, who last week co-hosted a presentation on Microsoft's fuzzing efforts at the CanSecWest security conference. 'While a large number, it's important to note that that doesn't mean we found 1,800 security issues. We also want to fix things that are not security concerns.'"
