CVE-2022-36934 An integer overflow in WhatsApp could result in remote code execution in an established video call.
In addition to being a major privacy concern, video calling is a very popular feature in many applications. Thus, any security issue in video chatting will have a major impact. If you are using WhatsApp on a mobile device, the chances of an integer overflow are very high. The best way to avoid such issues is to exchange information securely and offline.
WhatsApp: How you can limit video calls
For starters, WhatsApp video calls require the use of a mobile device and Wi-Fi to work. If you do not have access to these features, then you will not be able to make any video calls. This is why it is important that both parties exchange information securely offline first before they begin a video call.
A few other things you can do is to disable your camera during video chats or block users who are not authorized to see your chat history. You can also request for an audio call instead, which does not rely on Wi-Fi, but still allows for all the same capabilities. Why is this important? Because if someone has gained access to your mobile phone in order to view your conversations, they will still be able to hear what you say during an audio call.
Lastly, turn off any location services that might be automatically turned on during your video chats. The last thing you want is for a hacker to know where you are at all times!
How to Check if WhatsApp Is vulnerable to a buffer overflow?
In order to check if WhatsApp is vulnerable to a buffer overflow, you need to run the following command in a terminal:
bash -c 'printf "%i
"' $(dd if=/dev/urandom of=whatsapp.dat bs=1 count=1024)
This will generate an output of the number 1024. If this number is smaller than 256 or greater than 65536, it means that your file is not vulnerable to an integer overflow.

The best way to avoid any security issues in communications is by exchanging information securely. This method seems to be especially important in the case of video calling apps like WhatsApp, which are becoming more and more popular among users. One example of this is an integer overflow vulnerability that has been recently discovered and disclosed by the developer of WhatsApp.
The issue was uncovered by a security researcher who found that WhatsApp's video calling feature could be exploited for remote code execution on Mac and Windows devices. According to the developer, this vulnerability only affects machines with Intel processors and running Microsoft Windows, however systems with AMD processors are not affected.
How Did the WhatsApp Video Calling Website Get Hacked?
Video calling services have been plagued with security issues. Most recently, WhatsApp has fallen victim to a major vulnerability that could allow hackers to potentially access your WhatsApp account. The vulnerability was discovered by JonathanHE on April 2nd and is labeled CVE-2022-36934. If your device is running the latest version of the app, you will be protected from this exploit (update WhatsApp as soon as possible). However, if you are using an older version of WhatsApp or even the web interface, it is possible to be exposed to this exploit.
