Multiple Vulnerabilities in Google Chrome Could Allow for Arbitrary Code Execution

ITS Advisory Number: 
2019-095
Date(s) Issued: 
Wednesday, September 11, 2019
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 allow for arbitrary code execution. Google Chrome is a web browser used to access the Internet. Successful exploitation of the most severe 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 install programs; view, change, or delete data; or create new accounts with full user rights. 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.

 

THREAT INTELLIGENCE:

There are currently no reports of these vulnerabilities being exploited in the wild.

Systems Affected: 
  • Google Chrome versions prior to 77.0.3865.75

  • External URIs may trigger other browsers. (CVE-2019-5874)
  • Full screen notification overlap. (CVE-2019-13660)
  • Full screen notification spoof. (CVE-2019-13661)
  • Global window leak via console. (CVE-2019-13668)
  • Google URI shown for certificate warning. (CVE-2019-13676)
  • Heap overflow in Skia. (CVE-2019-5871)
  • HTTP authentication spoof. (CVE-2019-13669)
  • IDN spoof. (CVE-2019-13663)
  • IDN spoofing. (CVE-2019-13674)
  • IP address spoofing to servers. (CVE-2019-13680)
  • Multiple file download protection bypass. (CVE-2019-13665)
  • Out-of-bounds access in V8. (CVE-2019-5877)
  • SameSite cookie bypass. (CVE-2019-5880)
  • Side channel using storage size estimate. (CVE-2019-13666)
  • Site isolation bypass. (CVE-2019-13682)
  • URI bar spoof when using external app URIs. (CVE-2019-13667)
  • URL bar spoofing on iOS. (CVE-2019-5873)
  • URL bar spoof via download redirect. (CVE-2019-5875)
  • URL spoof. (CVE-2019-13659)
  • Use-after-free in media. (CVE-2019-5876, CVE-2019-5870)
  • Use-after-free in Mojo. (CVE-2019-5872)
  • Use-after-free in V8. (CVE-2019-5878)
  • User gesture needed for printing. (CVE-2019-13679)
  • V8 memory corruption in regex. (CVE-2019-13670)

 

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 the stable channel update 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.
