Let’s hold off just a little bit longer on our Firefox 3 downloads. I know we’re excited but security first.

Reprint from the TippingPoint Digital Vaccine Labs blog -

A number of people who monitor our Zero Day Initiative’s Upcoming Advisories page noticed yesterday that we reported a vulnerability to Mozilla (ZDI-CAN-349). Taking into account the coincidental timing of the Firefox 3.0 release, many are asking us if this is the first reported critical vulnerability in the latest version of the popular open source browser.

What we can confirm is that about five hours after the official release of Firefox 3.0 on June 17th, our Zero Day Initiative program received a critical vulnerability affecting Firefox 3.0 as well as prior versions of Firefox 2.0.x. We verified the vulnerability in our lab, acquired it from the researcher, then promptly reported the vulnerability to the Mozilla security team shortly after. Successful exploitation of the vulnerability could allow an attacker to execute arbitrary code. Not unlike most browser based vulnerabilities that we see these days, user interaction is required such as clicking on a link in email or visiting a malicious web page.

While Mozilla is working on a fix, we wont be divulging anything else until a patch is available, adhering to our vulnerability disclosure policy. Once the issue is patched, we’ll be publishing an advisory here. Working with Mozilla on past security issues, we’ve found them to have a good track record and expect a reasonable turnaround on this issue as well.

For more information on the Zero Day Initiative, you can read an intro.

With the new release of Firefox 3 this week I thought I’d take the opportunity to remind everyone of our supported platforms per our client contracts. FF3 does not fall in this range. Neither does WIN Vista or MAC 10.5. Not yet. Please make sure you test all work per the guidelines below. Thanks.

The 4th beta of the Firefox 3.0 browser was released Monday and includes more than 900 enhancements over the previous beta.

Mozilla said the new beta includes improvements to performance and memory usage, fixes for stability, and platform-specific enhancements. Some of the enhancements include a new download manager to make locating downloads easier; a full page zoom feature that allows you to zoom in and out of pages more easily; and integration for Vista, Mac OS X, and Linux that features platform-specific icons, buttons, and other user interface elements.
