Both Adobe and Microsoft on Tuesday issued patches to plug critical security holes in their products. Adobe’s Flash Player patch addresses 17 security flaws, including one “zero-day” bug that is already actively being exploited by attackers. Microsoft’s bundle of updates tackles at least 42 security weaknesses in Windows and associated software.
As per usual, the largest share of flaws fixed are in Microsoft’s browsers — Internet Explorer and Edge. Also included in the mix are updates for Microsoft Office and .NET.
As part of a new Microsoft policy that took effect in October, home and business Windows users will no longer be able to pick and choose which updates to install and which to leave for another time. Consumers on Windows 7 Service Pack 1 and Windows 8.1 will henceforth receive what Redmond is calling a “Monthly Rollup,” which addresses both security issues and reliability issues in a single update.
It’s important to note that several update types won’t be included in a rollup, including those released for Adobe Flash Player on Tuesday. The latest update brings Flash to v. 188.8.131.52 for Windows and Mac users alike. If you have Flash installed, you should update, hobble or remove Flash as soon as possible. To see which version of Flash your browser may have installed, check out this page.
The most recent versions of Flash should be available from the Flash home page. Windows users who browse the Web with anything other than Internet Explorer may need to apply this patch twice, once with IE and again using the alternative browser (Firefox, Opera, e.g.).
Chrome and IE should auto-install the latest Flash version on browser restart (users may need to manually check for updates in and/or restart the browser to get the latest Flash version). Chrome users may need to restart the browser to install or automatically download the latest version. When in doubt, click the vertical three dot icon to the right of the URL bar, select “Help,” then “About Chrome”: If there is an update available, Chrome should install it then.
