A new vulnerability was found on the older versions of WhatsApp.
Another security flaw has been found on the Facebook-owned WhatsApp but don’t worry if you’re using the latest version as it only affects older versions of the app. Sources explained that the vulnerability is able to give hackers a ‘cyber-attack vector’. This basically allows someone to hack into your device once you download an infected MP4 file.
This somewhat special MP4 file is able to execute a remote code that will be able to snoop around your devices – this vulnerability affects both Android and iOS users. Downloading the MP4 file will run the code and is now classified as ‘critical’.
A post by Facebook detailed the vulnerability: “A stack-based buffer overflow could be triggered in WhatsApp by sending a specially crafted MP4 file to a WhatsApp user. The issue was present in parsing the elementary stream metadata of an MP4 file and could result in a DoS or RCE.”
If you’re running the latest version of WhatsApp on your iOS or Android device, then you don’t need to worry since it affects only older versions. To be specific, the affected WhatsApp versions include Android versions before 2.19.274, iOS versions before 2.19.100, Business for Android before 2.19.104, Business for iOS versions before 2.19.100 and Windows Phone versions before/including 2.18.368.
