TECHNICAL SUMMARY:
Multiple vulnerabilities have been discovered in Google Chrome, the most severe of which could allow for arbitrary code execution. Details of the vulnerabilities are as follows: 

• CVE-2022-0971: Use after free in Blink Layout
• CVE-2022-0972: Use after free in Extensions
• CVE-2022-0973: Use after free in Safe Browsing
• CVE-2022-0974: Use after free in Splitscreen

• CVE-2022-0978: Use after free in ANGLE
• CVE-2022-0979: Use after free in Safe Browsing
• CVE-2022-0980: Use after free in New Tab Page
  ‍

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.

RECOMMENDATIONS:
We recommend the following actions be taken:

• Apply the stable channel update provided by Google to vulnerable systems immediately after appropriate testing.
• Run all software as a non-privileged user (one without administrative privileges) to diminish the effects of a successful attack.
• Remind users not to visit un-trusted websites or follow links provided by unknown or un-trusted sources.
• Inform and educate users regarding the threats posed by hypertext links contained in emails or attachments especially from un-trusted sources.
  ‍

Apply the Principle of Least Privilege to all systems and services.
