Multiple Vulnerabilities in Google Chrome Could Allow for Arbitrary Code Execution
MS-ISAC ADVISORY NUMBER:2016-081
Multiple vulnerabilities have been discovered in Google Chrome, the most severe of which could result in arbitrary 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 allow an attacker to execute arbitrary code in the context of the browser, obtain sensitive information, bypass security restrictions, or cause denial-of-service conditions.
There are currently no reports of these vulnerabilities being exploited in the wild.

Multiple vulnerabilities have been discovered in Google Chrome. These vulnerabilities can be triggered by a user visiting a specially crafted web page. Details of these vulnerabilities are as follows:
A same origin bypass vulnerability in DOM. (CVE-2016-1667)
A same origin bypass vulnerability in Blink V8 bindings. (CVE-2016-1668)
A buffer overflow in V8. (CVE-2016-1669)
A race condition in loader. (CVE-2016-1670)
A directory traversal vulnerability using file scheme on Android. (CVE-2016-1671)
Successful exploitation of these vulnerabilities could allow an attacker to execute arbitrary code in the context of the browser, obtain sensitive information, bypass security restrictions, or cause denial-of-service conditions.
We recommend the following actions be taken:
Apply appropriate patches provided by Google to vulnerable systems immediately after appropriate testing.
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.
Inform and educate users regarding the threats posed by hypertext links contained in emails or attachments especially from un-trusted sources.
