Who is Vulnerable?
Vulnerability Description	Google Chrome is a web browser developed by Google Inc. It provides rich web browsing similar to other web browsers such as Firefox, Opera, and Internet Explorer. Chrome is unique from other browsers because it follows a multi-process architecture: by default, a separate process is allocated to each site instance and plugin. A security bypass vulnerability exists in Google Chrome. The vulnerability is due to a design weakness within Chrome's automatic download navigation component. A remote attacker could exploit this vulnerability by enticing a target user to visit a malicious web page using the affected application. Successful exploitation could result in execution of arbitrary code on the vulnerable system in the context of the logged-on user.
