Vulnerabilities in Google Chrome Could Allow for Arbitrary Execution

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.

• Insufficient policy enforcement in Background Fetch. (CVE-2022-2610)
• Inappropriate implementation in Fullscreen API. (CVE-2022-2611)
• Side-channel information leakage in Keyboard input. (CVE-2022-2612)
• Use after free in Input. (CVE-2022-2613)
• Use after free in Sign-In Flow. (CVE-2022-2614)
• Insufficient policy enforcement in Cookies. (CVE-2022-2615)
• Inappropriate implementation in Extensions API. (CVE-2022-2616)
• Use after free in Extensions API. (CVE-2022-2617)
• Insufficient validation of untrusted input in Internals. (CVE-2022-2618)
• Insufficient validation of untrusted input in Settings. (CVE-2022-2619)
• Use after free in WebUI. (CVE-2022-2620)
• Use after free in Extensions. (CVE-2022-2621)
• Insufficient validation of untrusted input in Safe Browsing. (CVE-2022-2622)
• Use after free in Offline. (CVE-2022-2623)
• Heap buffer overflow in PDF. (CVE-2022-2624)

Successful exploitation of the most severe of these vulnerabilities could allow for arbitrary code execution in the context of the logged-on user. Depending on the privileges associated with the user, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights. 

Affected Products

Risk

• High for large, medium, and small government entities and organisations.

 Recommendations

• 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.
