Firefox updates for eight critical flaws

Mozilla has released an update to its Firefox browser to patch 14 vulnerabilities, eight of which are defined as "critical" in severity, meaning users' machines can be infected with malware simply by visiting a website — a tactic known as a drive-by download. Firefox version 3.6.7 and 3.5.11, released Tuesday, also corrects two flaws rated "high" and four bugs deemed "moderate." — DK
