Subject: 
Multiple Vulnerabilities in Google Chrome Could Allow for Remote Code Execution
Overview: 

Multiple vulnerabilities have been discovered in Google Chrome, the most severe of which could result in remote code execution. Google Chrome is a web browser used to access the Internet. These vulnerabilities can be exploited if a user visits, or is redirected to, a specially crafted web page. Successful exploitation of these vulnerabilities could allow an attacker to execute remote code in the context of the browser, obtain sensitive information, bypass security restrictions, or cause denial-of-service conditions.

Successful exploitation of these vulnerabilities could allow an attacker to execute remote code in the context of the browser, obtain sensitive information, bypass security restrictions, or cause denial-of-service conditions.

Actions: 
  • After appropriate testing, immediately apply updates provided by Google to vulnerable systems.

  • 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 system and service.
