Insider Causes and Solutions for "Adobe Flash Player Blocked Due to Expiration"

Is Flash really overwhelmed by Facebook's chief security officer Stamos? Today, Xiaobian and many colleagues who use Chrome browser have encountered "Adobe Flash Player is blocked due to expirationThis directly leads to the inability of many Flash-based images and applications on the web page, and many colleagues who use other browsers have also encountered this situation. Then I tried maxthon, the second browser on my computer, and it didn't have this problem, and at this point, I guessed what was going on......

　　◆Cause

Listen to me slowly, this is the same as what we followed up and reported not long agoHacking Team (hereinafter referred to as HT) 400GB internal data leakedThe events are very connected. If you talk about Stamos's sentence"It's time for Adobe to turn off Flash"If it can only be regarded as a prophecy, the leaked data in the HT incident is the direct trigger. If Flash can't escape its fate this time, it will never forget these 400GB of data.

Facebook's chief security officer Stamos tweeted yesterday

Let's take a look at what happened yesterday.

Just a few days after the HT leak, Flash was exposed to three 0-day high-risk vulnerabilities: CVE-2015-5119, CVE-2015-5122, and CVE-2015-5123. On the 13th, yesterday, FireFox issued an announcement announcing the complete ban on Flash. Today, it seems that not only FireFox, but also the action to block Flash Player plugins has spread to other companies, and this is a big deal......

After the incident, many users who did not know the truth tried to uninstall and reinstall Flash Player, but they still couldn't solve it, repeatedly testing the patience of users.

In this regard, Adobe once again urgently released the latest one18.0.0.209version to fix ...... You know, version 18.0.0.203 has just been updated. Frequent updates and patches in a few days, outsiders watch the fun, but in the eyes of practitioners, your problem is big. Could it be that Mr. Qiao really said that Flash is already old? In the face of frequent security issues and often "dragging" browsers and even crashing for no reason, is there really no one who can save Flash?

If Adobe can't come up with a solution, maybe the era of HTML5 is really coming.

In February this year, YouTube, the world's largest video website, announced that it would use HTML5 instead of Flash for video playback by default. For the accumulated resentment,Adobe, however, has behaved unusually calmly, saying that it will not give up on this product. Adobe executive Paul Burnett believes that "the future of Flash is in web games".

From the user's point of view, the editor wants to say that we don't care about your old and new technology, it doesn't matter if Flash is old or H5 new, we just want to see a smooth + safe experience, if it can't be solved again and again, there is only the fate of being abandoned by the times.

　　◆Solution

Regardless of what the future holds for Flash, the only way to fix "Adobe Flash Player blocked due to expiration" is to update it as soon as possible18.0.0.209version, or try other alternate browsers to try your luck, there is no other way. Monopoly, there is no way.

It should be noted that some netizens reported that installing the latest version did not solve the problem, and the web page Flash was still not normal. At this time, I recommend that you check the list of browser plugins to confirm18.0.0.209The Flash Player replaces the old version. This is very important, because many browsers have problems with adaptation plugins, so you must confirm that the new version of Flash has been adapted in place after installation.

Let me take Chrome as an example, Chrome users will almost always encounter it after installing the new version, that is, the browser will "enable" the old and new versions at the same time by default, instead of replacing or disabling the old version (not smart!). The solution is very simple, open the Chrome plug-in list (the browser can directly enter chrome://plugins/), find the Adobe Flash Player item, "deactivate" the old version, and note that it is to change "enable" to "disable" (not smart!). At this time, the deactivated version will be "grayed out", as shown in the figure:

Open the webpage and try it, the prompt changes, click "Always run". I haven't tested other browsers, and the most reliable and safe way now is to successfully adapt the browser to the latest version18.0.0.209Adobe Flash Player, users using other browsers can also follow the above ideas to confirm whether the adaptation is successful.

In fact, there is a shortcut to solve this problem, but it is definitely [risky approach], that is, directly change the exe program target, add the command "--allow-outdated-plugins", note that a space must be added before --, as shown in the figure:

I must reiterate that this method is risky! Even if we don't understand technology, we can find out what allowed outdated plugins mean,"Allows loading expired pluginsThis is a big taboo in the safety circle! I put it here to tell everyone not to try to use this method conveniently, and fall into the trap of some ill-intentioned people on the Internet. Flash is inherently fragile and vulnerable, so you can imagine the risk of loading outdated plugins.

Write these first, if it helps, everyone is welcome to share the article, and then help a group of other friends who are in a hurry to solve the problem yet. In addition, I only mentioned the details of Chrome's solution in the article, so users who use other browsers are welcome to share the solution with you and exchange experiences together.
