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 22.214.171.124 (download). Google has built Chrome so it updates itself automatically with no user intervention, though the software must be restarted for the new version to run.
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.
