[German]Adobe has released Flash Player Version 184.108.40.206. Because it’s an out-of-band update, I guess, it fixes vulnerabilities. It might be the third Flash update for October 2017.
If you have activated the auto-update function of the Flash-Player and installed the player separately, you should receive this update automatically. For Windows 8.1 and Windows 10 I assume that Microsoft will roll it out. Also Chrome Browser should be updated automatically.
Which Flash Player version do I have?
The installed Flash version can be checked on this Adobe website. The site shows also, if the Flash-Player is supported in the browser, which version is used and which version is available for update at Adobe.
If you update your Flash Player via this Adobe page, take care to untick the optional offers (see screenshot above for McAfee Security Scan Plus, True Key from Intel etc.). Check this page and here, if you are in need of an uninstaller and more.
