There’s another new version of Flash: 22.214.171.124. A single Critical security vulnerability is addressed in this version. The vulnerability, when exploited, can allow for arbitrary code execution.
If you’re using a web browser with Flash enabled, you should update it as soon as possible. If you’re not sure whether your browser is enabled for Flash content, head over to the Flash Player Help page. If Flash is installed and enabled in your browser, your Flash version will be shown.
You can install Flash by visiting the main Flash installer page. Make sure to disable all the optional installation checkboxes on that page, or you’ll get unwanted software along with Flash.
As usual, Google Chrome and Microsoft’s browsers, which have their own embedded Flash viewers, are updated separately. Chrome will update itself; Edge and Internet Explorer are updated via the Windows Update service.
