Until a patch is released, a security hole--known as a zero-day vulnerability--in effect makes your computer a sitting duck for anyone who writes an exploit for it and bothers to distribute it via e-mails and drive-by downloads on Web sites.
EEye Digital Security launched a Web site yesterday that lists current zero-day vulnerabilities and offers an archive on ones that have been patched. The Zero Day Tracker compiles information on publicly disclosed security holes and provides details on them including what software they affect, how severe they are, the potential impact and suggestions for workarounds and other protection techniques.
Marc Maiffret, co-founder and chief technology officer of eEye, describes the free site as a "one-stop shop" for zero-day information. "For the longest time the only company that would notify you about zero-days was Microsoft, and recently Adobe has started doing that," he said. "But there are still many other companies that have zero-day vulnerabilities that go unreported."
