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 are no reports that these vulnerabilities are being exploited in the wild.

SYSTEMS AFFECTED:

Google Chrome version 97.0.4692.71

RISK:
Government:

Large and medium government entities: High
Small government entities: Medium

Businesses:

Large and medium business entities: High
Small business entities: Medium

Home users: Low

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:

Use after free in Storage. (CVE-2022-0096)
Inappropriate implementation in DevTools. (CVE-2022-0097)
Use after free in Screen Capture. (CVE-2022-0098)
Use after free in Sign-in. (CVE-2022-0099)
Heap buffer overflow in Media streams API. (CVE-2022-0100)
Heap buffer overflow in Bookmarks. (CVE-2022-0101)
Type Confusion in V8. (CVE-2022-0102)
Use after free in SwiftShader. (CVE-2022-0103)
Heap buffer overflow in ANGLE. (CVE-2022-0104)
Use after free in PDF. (CVE-2022-0105)
Use after free in Autofill. (CVE-2022-0106)

Inappropriate implementation in Compositing. (CVE-2022-0116)
Policy bypass in Service Workers. (CVE-2022-0117)
Inappropriate implementation in WebShare. (CVE-2022-0118)
Inappropriate implementation in Passwords. (CVE-2022-0120)

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.
