Description: 

Multiple vulnerabilities have been discovered in Google Chrome. These vulnerabilities can be triggered by a user visiting a specially crafted web page. Details of these vulnerabilities are as follows:

  • Same-origin bypass vulnerability in Blink  (CVE-2016-1629)
  • Sandbox escape vulnerability in Chrome (CVE-2016-1629)

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

Actions: 
  • Apply appropriate patches 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.
