Adobe has released a new update for Flash Player on July 11, as mentioned on its security bulletin APSB17-21. This brings the web client to version 18.104.22.168.
The latest update provides security patches for three vulnerabilities. CVE-2017-3099, which is classified as a critical vulnerability, can result to remote code execution through memory corruption. CVE-2017-3080, which is classified as an important vulnerability, can lead to the disclosure of users’ information through security bypass. CVE-2017-3100, another important vulnerability, can cause the disclosure of users’ memory address through memory corruption.
These vulnerabilities affect Adobe Flash Player Desktop Runtime version 22.214.171.124 and earlier (which is available for Windows, Mac, and Linux computers) as well as Adobe Flash Player for Google Chrome version 126.96.36.199 and earlier (which runs on Windows, Mac, Linux and Chrome OS computers). The vulnerabilities also affect Adobe Flash Player for Microsoft Edge and Internet Explorer 11 version 188.8.131.52 and earlier, which runs on Windows 8.1 and Windows 10 computers.
Check Your System Now
If you’re not sure what Flash Player version you have on your computer, you can verify by going to get.adobe.com/flashplayer/about. The page will show the version that’s installed on the browser you’re using. Another way to verify your Flash Player version is to open any Flash-based content on your browser, right-click on the content, and choose “About Adobe Flash Player” or “About Macromedia Flash Player”.
If you use different browsers in your computer, you need to take the steps above for each browser. It’s always possible that each browser in your computer has a different version of Adobe Flash Player installed in it.
Updating Adobe Flash Player
If you have previously allowed Adobe Flash Player to automatically update itself, you no longer need to do anything to get version 184.108.40.206. However, Flash Player will still notify you about the update and give you the option to manually install it instead of waiting for the automatic updating to kick in.
If you have not enabled automatic updates, you’ll need to manually download and install version 220.127.116.11. To do this, open your web browser, go to get.adobe.com/flashplayer, then click on the “Install Now” button. You can also uncheck the boxes beside the optional offers if you don’t want to download the free programs offered by Adobe. Once the installation file has been downloaded, find it in your downloads folder, double-click on the file to launch it, and follow the instructions on the screen to install the update.
You can also update Flash Player on each individual browser. If you’re using Mozilla Firefox, click on the hamburger menu on the upper right part of the screen and choose “Add-ons”. Look for “Shockwave Flash”, click on the “Options” button beside it, then click on the gear icon to bring down a drop-down menu. Choose “check for updates” and wait for Firefox to find and install updates.
If you’re using Google Chrome, open a new tab, type “chrome://components” on the address bar, then press Enter. Search for “Adobe Flash Player” and check what version is installed on the browser. If it’s version 18.104.22.168 or earlier, click on the “Check for update” button and wait for Chrome to find and install updates.
