NY.gov Portal State Agency Listing
The following cyber advisory was issued by the New York State Office of Information Technology Services and is intended for State government entities. The information may or may not be applicable to the general public and, accordingly, the State does not warrant its use for any specific purposes.

ITS ADVISORY NUMBER:
2014-040

DATE(S) ISSUED:
4/28/2014

SUBJECT:
Multiple Vulnerabilities in Google Chrome Could Allow 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 may result in an attacker gaining the same privileges as the logged on user. 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 34.0.1847.131 for Windows and Mac
  • Google Chrome Prior to 34.0.1847.132 for Linux

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

DESCRIPTION:
Six vulnerabilities have been reported in Google Chrome. Details of the vulnerabilities are as follows:

  • A security vulnerability exists due to a type confusion error in V8. [CVE-2014-1730]     
  • A security vulnerability exists due to a type confusion error in DOM. [CVE-2014-1731]   
  • A use-after-free vulnerability exists in the Speech Recognition. [CVE-2014-1732]                                                     
  • A security vulnerability exists that occurs due to an error in the compilation of 'Seccomp-BPF'. [CVE-2014-1733]           
  • Multiple security vulnerabilities exist due to an unspecified error. [CVE-2014-1734]     
  • Multiple security vulnerabilities exist due to an unspecified error in V8. [CVE-2014-1735]

Successful exploitation may result in an attacker gaining the same privileges as the logged on user. 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.

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.
  • Remind users not to open email attachments from unknown users or suspicious emails from trusted sources.
