Google has released a new version, 13·0·782·215, of its Chrome browser, for all platforms (Linux, Mac OS X, Windows, and Chrome Frame). This release includes fixes for 11 identified security vulnerabilities; of these, one is rated Critical, nine High, and one Medium. (Some of the fixes only apply to certain platforms.) More details are available in the release announcement on the Chrome Releases blog.
Windows users should get the new version via the built-in automatic update mechanism; you can verify that your system has been updated by clicking on the tools menu (the little wrench), and then on “About Google Chrome”. Linux users can get the updated package using their distros’ usual update tools.
