OVERVIEW:

       A vulnerability has been identified in Google Chrome prior to version
       1.0.154.59.


IMPACT:

       The vendor describes the vulnerability as:
       "CVE-2009-1340 ChromeHTML protocol handler same-origin bypass
       An error in handling URLs with a chromehtml: protocol could allow an 
       attacker to run scripts of his choosing on any page or enumerate files 
       on the local disk under certain conditions.
       
       If a user has Google Chrome installed, visiting an attacker-controlled 
       web page in Internet Explorer could have caused Google Chrome to launch, 
       open multiple tabs, and load scripts that run after navigating to a URL 
       of the attacker's choice." [1]


MITIGATION:

       Google recommends upgrading to the latest version of Google Chrome,
       which can be obtained from: http://www.google.com/chrome
