Google has released a new version, 18·0·1025·168, of its Chrome browser, for all platforms: Windows, Linux, Mac OS X, and Chrome Frame. This new version fixes five identified security flaws, three of which Google rates as High severity. Further information on these changes is in the release announcement.
Windows and Mac users should get the new version via the built-in update mechanism. Linux users should get the updated package from their distributions’ repositories, using their standard package maintenance tools. You can verify that your system has been updated by clicking on the tools menu (the little wrench), and then on “About Google Chrome”.
