      Correct answer: CVE-2019-11932 is a vulnerability in the android-gif-drawable library. Yet the CVE text doesn't mention "android-gif-drawable". It only mentions WhatsApp. I'm aware of over 28,400 free Android apps that use this library. I wonder how many app authors are aware?

      For example, here's a demonstration of viewing a crafted message with an app called Chomp SMS. It has over 10 million installs and also uses android-gif-drawable. When @facebook created the entry for CVE-2019-11932, they neglected to mention anything other than WhatsApp.pic.twitter.com/dYJJp2bUOz

      Though I was not aware of the names of other vulnerable apps, I did mention that threat in my article published in October. 28,400 Android app is a dangerous sign. Do you have any plan to list most popular of them anytime soon?pic.twitter.com/cF53N1v5YJ

      Actually, I just updated the gist to include the download counts. And it's sorted in descending order. Should be more useful than the original alphabetic listing.
