Multiple Vulnerabilities in Google Chrome Could Allow for Remote Code Execution

ITS Advisory Number:

Date(s) Issued:

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

Multiple vulnerabilities have been discovered in Google Chrome that 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 result in an attacker gaining the same privileges as the user running the affected application. 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.

Systems Affected: 
  • Google Chrome Prior to 36.0.1985.143

Description: 

Twelve unspecified vulnerabilities were identified in Google Chrome. Three of the critical vulnerabilities are noted:

  • A use-after-free vulnerability that existed in web sockets. [CVE-2014-3165]
  • An information disclosure vulnerability due to an error in SPDY. Attackers can exploit this issue to obtain sensitive information. [CVE-2014-3166]
  • Various fixes from internal audits, fuzzing, and other initiatives. [CVE-2014-3167]

Successful exploitation could result in an attacker gaining the same privileges as the user running the affected application. 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. Failed exploit attempts will likely cause denial-of-service conditions.

Actions: 

We recommend the following actions be taken:

  • Update vulnerable Google Chrome products immediately after appropriate testing by following the steps outlined by Google.
  • 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.
  • Remind users not to open email attachments from unknown users or suspicious emails from trusted sources.
