The Firefox Web browser has apparently come of age, so to
speak. The latest security advisory from Secunia lists a whopping 21
vulnerabilities, and Mozilla has released a new
of the browser.


A slew of vulnerabilities has surfaced in the Mozilla
Firefox browser, affecting versions 0.x and 1.x. The threats involve multiple
critical cross-site scripting and phishing-related vulnerabilities, among

Secunia lists the following threats in Security Advisory 19631, “Firefox
Multiple Vulnerabilities”: CVE-2006-0748,

The worst of these vulnerabilities would permit the
execution of arbitrary code on the victim’s machine.


These vulnerabilities affect all older versions of Firefox,
beginning with version 1.5.

Risk level

Secunia has rated this group of vulnerabilities as highly


The only real way to
address this daunting array of threats
is to upgrade to Firefox version 1.0.8 or,
depending on your product track.

Final word

If you’re a Firefox user, you need the upgrade. If you’re not
a Firefox user, don’t let this recent spate of vulnerabilities intimidate you.

The latest version of the browser is far more than a
vulnerability patch, and I suggest you check out the features it includes.
While I’m not that enthusiastic about the new automatic update tool feature because
of security reasons, many users will like it because it lets Firefox
automatically make small background updates to the product.

And don’t forget about extensions. There are currently more
than 1,400 available add-ons and scores of really neat extensions. For more
information, check out the Firefox Add-ons Web page,
which is itself in beta.
