ITS ADVISORY NUMBER:
Multiple Vulnerabilities in Google Chrome Could Allow Remote Code Execution
Multiple vulnerabilities have been discovered in Google Chrome that could allow remote code execution 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 could result in an attacker gaining the same privileges as the logged on user. 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.
- Google Chrome prior to 32.0.1700.76 for Windows and Google Frame
- Google Chrome prior to 32.0.1700.77 for Mac and Linux
- Large and medium government entities: High
- Small government entities: High

Multiple vulnerabilities have been discovered in Google Chrome. Details on some of these vulnerabilities are as follows:
- CVE-2013-6646: Use-after-free in web workers.
- CVE-2013-6641: Use-after-free related to forms.
- CVE-2013-6642: Address bar spoofing in Chrome for Android
- CVE-2013-6643: Unprompted sync with an attacker's Google account
- CVE-2013-6645: Use-after-free related to speech input elements
- CVE-2013-6644: Various fixes from internal audits, fuzzing and other initiatives
Successful exploitation of some of the above vulnerabilities could result in an attacker gaining the same privileges as the user. Depending on the privileges associated with the user, an attacker could install programs; view, change, delete data; or create new accounts with full user rights.
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.
