FYI
According to CERT's (part of Homeland Security nowadays) email of today: Abode Flash Player has released an update due to security issue. I use Google Chrome and did manage to install the update. (I hope.) CERT also recommends this for all browsers you use.
But I have checked to see if Chrome has been updated and it is still showing the same Version.
The Chrome version of Flash Player has just updated on my machine.
Hello Miss Wanda
This page tell you what the version the browser that navigates to it is using. It has the current version numbers for other browsers and links to get an update just the same as the Flash add-on notifies you of:
https://www.adobe.com/software/flash/about/
This next page has links to get a fresh download of Flash's installer for each different browser or system.
The built in update process always fails for me because it looks for my proxy's "dll" in the folder name of the publisher instead of my ISP folder. My ISP re--sells the acceleration access. The built in update process link can't be paused but this one can. The installer is portable and may be copied and put on other systems rather than out of your data download budget.

You don't mention which Chrome version you have on your machine - You can check here if you have the latest version for you OS.
You can check which Adobe Flash player version is (automatically) installed on your machine by typing "chrome://plugins" (without quotes) in Chrome address bar.
There are two versions one 23.0.0.205 For Firefox and one 23.0.0.205 for IE 6,7,8,9,10,11 (18.5 mb) IE10 , IE11 on Windows 8.0,8.1,10 and on windows 10 EDGE and chrome have there own built in updater.
