Multiple vulnerabilities have been discovered in Google Chrome, the most severe of which could allow for arbitrary code execution. Google Chrome is a web browser used to access the Internet. Successful exploitation of the most severe of these vulnerabilities could allow an attacker to execute arbitrary code in the context of the browser. Depending on the privileges associated with the application, an attacker could view, change, or delete data. If this application has been configured to have fewer user rights on the system, exploitation of the most severe of these vulnerabilities could have less impact than if it was configured with administrative rights.
THREAT INTELLIGENCE:
There is currently no reports of these vulnerabilities being exploited in the wild.

After appropriate testing, immediately apply the stable channel update provided by Google to vulnerable systems.
-
Run all software as a non-privileged user (one without administrative privileges) to diminish the effects of a successful attack.
-
Apply the Principle of Least Privilege to all systems and services.
