New Vulnerability Discovered in Google Chrome

A cybersecurity advisory was issued yesterday, August 27, 2019, regarding a vulnerability in Google Chrome. The vulnerability could allow an attacker to execute arbitrary code, which could potentially lead to a breach.

What It Is:
A vulnerability has been discovered in Google Chrome, which could allow for arbitrary code execution. Google Chrome is a web browser used to access the Internet.

Successful exploitation of this vulnerability 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 install programs; view, change, or delete data; or create new accounts with full user rights. 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.
