Google released a new version of its Chrome browser Thursday to fix a high-severity security problem.
The problem affects Google's mainstream stable version of Chrome and is fixed in the
new version 1.0.154.59 (

The security problem, reported April 8 by Roi Saltzman of the IBM Rational Application Security Research Group, allowed cross-site scripting attacks. Such methods can make a Web browser process unauthorized code such as JavaScript, enabling a variety of attacks, including impersonation or phishing.
Mark Larson, Google Chrome program manager, described the problem this way in a blog posting Thursday:
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. Such an attack only works if Chrome is not already running.
