ITS ADVISORY NUMBER:
2013-101

DATE(S) ISSUED:
10/16/2013

SUBJECT:
Multiple Security Vulnerabilities reported in Google Chrome

OVERVIEW:

Multiple vulnerabilities have been discovered in Google Chrome that could allow remote code execution, bypass of security restrictions, or cause denial-of-service conditions. 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 may result in either an attacker gaining the same privileges as the logged on user, or gaining session authentication credentials. Depending on the privileges associated with the user, an attacker could install programs; view, change, or delete data; or create new accounts with full user rights. 

SYSTEM AFFECTED:

  • Google Chrome Prior to 30.0.1599.101

RISK:
Government:

  • Large and medium government entities: High
  • Small government entities: High

Businesses:

  • Large and medium business entities: High
  • Small business entities: High

Home users: High

RECOMMENDATIONS:
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.
