Although Google has already released a patch in the early days of this month in the bid to address this vulnerability, apparently, millions of the Android devices are still waiting for the latest Android security update that requires to be delivered by their respective device manufacturers. Google has described the vulnerability in its July Android Security Bulletin as the most severe vulnerability in this section [media framework] could enable a remote attacker using a specially created file to execute arbitrary code within the context of a privileged process. The fact that makes the issue more critical is that the Germany-based Android developer Marcin Kozlowski has uploaded a proof-of-concept for this attack on Github. Though the PoC that has been shared by Kozlowski, an HEVC encoded Video, only crashes the media player, it can help potential attackers develop their exploits to achieve RCE on targeted devices.

Nevertheless, it should also be noted that in case such malicious Videos are received through an instant messaging app such as the WhatsApp or Facebook Messenger or even uploaded on a service like YouTube or Twitter, the attack, however, will not work. This is because these services usually compress Videos and re-encode media files which distort the embedded-malicious code. The best way to protect yourself from this attack is to make sure that you update your mobile OS as soon as the latest patch is made available. In the meantime, you are also recommended to avoid downloading and playing random Videos from any untrusted sources and also follow the basic security and privacy practices.
