Sure Firefox 3 is a fast browser, but who knew it would take only five hours after its release Tuesday to find its first vulnerability? Baby grows up so quickly.
Contributors to the Zero Day Initiative program recorded Firefox 3's first vulnerability before it was confirmed and exposed by the group Wednesday. The vulnerability allows attackers to run programs on any Firefox user's computer. To expose the vulnerability, victims would have to click on the wrong link first.
The Zero Day Initiative is a program founded by TippingPoint dedicated to exposing security issues in software.
Adhering to etiquette, the report won't dive into any more specifics until Mozilla has a chance to repair the vulnerability. If it makes you feel any better, the vulnerability extends to Firefox 2 as well -- meaning Firefox users have been living with it for a long time without even knowing. Who knows what else might be out there?
