The Firefox browser has been updated for four security flaws, three of which were rated as “critical,” according to Mozilla.
“Mozilla has released a security advisory to address multiple vulnerabilities,” an advisory from US-CERT said. “These vulnerabilities may allow an attacker to execute arbitrary code, mislead users by spoofing a URL, or cause a denial-of-service.”
Another update from Mozilla addressed problems in an older version of Firefox (3.0.14).
In a post on the Mozilla blog, Nicole Loux, who is "public relations practitioner and messaging masseuse" for Mozilla, encouraged users to upgrade immediately.
“We strongly recommend that all Firefox users upgrade to this latest release,” she wrote. “If you already have Firefox 3.5 or Firefox 3, you will receive an automated update notification within 24 to 48 hours.”
With the updates, users will be notified if they are running a vulnerable version of the Adobe Flash Player, enabling them to avoid crashes, stability issues and other security problems.
