GOOGLE CHROME SECURITY WARNING: THIS IS LONG, BUT YOU NEED TO KNOW. SENT OUT TODAY. Subject: UPDATED - MS-ISAC CYBER SECURITY ADVISORY - Multiple Vulnerabilities in Google Chrome Could Allow Remote Code Execution - RISK: HIGH - TLP: WHITE TLP:WHITE MULTI-STATE INFORMATION SHARING AND ANALYSIS CENTER CYBER SECURITY ADVISORY MS-ISAC ADVISORY NUMBER: 2013-099 - Updated DATE(S) ISSUED: 10/11/2013 10/15/2013 - Updated SUBJECT: Multiple Vulnerabilities in Google Chrome Could Allow Remote Code Execution OVERVIEW: Multiple vulnerabilities have been discovered in Google Chrome that could allow remote code execution, bypass of security restrictions, spoof the displayed uniform resource identifier URI in the address bar, or cause denial-of-service conditions. Google Chrome is a web browser used to access the Internet. Details are not currently available that depict accurate attack scenarios, but it is believed that some of the 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. October 15 UPDATED OVERVIEW: Google has identified additional vulnerabilities in Chrome and has issued an update which mitigates these vulnerabilities.

[CVE-2013-2921] · A use-after-free issue in template element. [CVE-2013-2922] · Multiple unspecified issues affect the application. [CVE-2013-2923] · A use-after-free in ICU. [CVE-2013-2924] October 15 UPDATED DESCRIPTION: · A use-after-free in XHR. [CVE-2013-2925] · A use-after-free in editing. [CVE-2013-2926] · A use-after-free in forms. [CVE-2013-2927] · Multiple unspecified issues affecting the application. [CVE-2013-2928] 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. Failed exploit attempts will likely cause denial-of-service conditions. 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. · Do not open email attachments or click on URLs from unknown or un-trusted sources.
