It’s another Patch Tuesday, and this month we have the usual pile from Microsoft, along with a new version of Flash.

Analysis of the summary spreadsheet — helpfully provided by Microsoft on the Security Update Guide site — shows that there are forty-nine updates, addressing eighty vulnerabilities in Windows, Internet Explorer, .NET, Edge and Office. Seventeen of the vulnerabilities are critical.

Those of you running Windows 10 will get these updates automatically, unless you’ve explicitly configured Windows to delay updates. Everyone else should navigate to Windows Update in the Windows Control Panel or Windows Settings.

The new version of Flash is 32.0.0.255. It addresses two critical security bugs in earlier versions, both of which were discovered and reported by independent security researchers.

Anyone who still uses Flash, especially if it’s enabled in any web browser, should update Flash as soon as possible. Go to the Flash applet in the Windows Control Panel to check your version and install the new version.
