Google just released a major security update for Google Chrome that addresses eleven vulnerabilities, including two zero-day flaws that have been exploited in the wild. A remote attacker might take use of the flaws by tricking an unsuspecting victim into visiting a specially designed website they generated, which would cause a type confusion error, allowing them to run arbitrary code on the affected system. Users are advised to update their browsers to the latest version (91.0.4472.164) as soon as practicable.
