Date(s) Issued: 
Tuesday, June 6, 2017
Subject: 
Multiple Vulnerabilities in Google Chrome Could Allow for Arbitrary Code Execution
Overview: 

Multiple vulnerabilities have been discovered in Google Chrome, the most severe of which could result in arbitrary 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 the most severe of these vulnerabilities could allow an attacker to execute arbitrary code in the context of the browser, obtain sensitive information, bypass security restrictions and perform unauthorized actions, or cause denial-of-service conditions.

Systems Affected: 
  • Google Chrome prior to 59.0.3071.86

Description: 

Multiple vulnerabilities have been discovered in Google Chrome, the most severe of which could result in 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:

  • Type confusion in the V8 (CVE-2017-5070).
  • Out-of-bounds read in the V8 (CVE-2017-5071).
  • Address spoofing in Omnibox (CVE-2017-5072, CVE-2017-5086, CVE-2017-5076).
  • Use after free in print preview (CVE-2017-5073).
  • Use after free in Apps Bluetooth (CVE-2017-5074).
  • Information-disclosure in CSP reporting (CVE-2017-5075).
  • Heap overflow in Skia (CVE-2017-5077).
  • Command injection in mailto handling (CVE-2017-5078).
  • UI spoofing in Blink (CVE-2017-5079, CVE-2017-5083).
  • Use after free in credit card autofill (CVE-2017-5080). 
  • Security-bypass in extension verification (CVE-2017-5081). 
  • Insufficient hardening in credit card editor (CVE-2017-5082). 
  • Inappropriate javascript execution on WebUI pages (CVE-2017-5085). 

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

Actions: 
  • After appropriate testing, immediately apply patches 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 systems and services.
