Chrome Stable Channel Update for Desktop – February 2021

Technical Summary

Multiple vulnerabilities have been discovered in Google Chrome, the most severe of which could allow for arbitrary code execution. These vulnerabilities can be exploited if a user visits, or is redirected to, a specially crafted web page.

Details of the vulnerabilities are as follows:

· A use after free vulnerability in Payments (CVE-2021-21142)

· A heap buffer overflow vulnerability in Extensions (CVE-2021-21143)

· A heap buffer overflow vulnerability in Tab Groups (CVE-2021-21144)

· A use after free vulnerability in Fonts (CVE-2021-21145)

· A use after free vulnerability in Navigation (CVE-2021-21146)

· An inappropriate implementation vulnerability in Skia (CVE-2021-21147)

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.
