What's New Security Vulnerability

The government agency claims that multiple vulnerabilities have been reported in the instant messaging app. These vulnerabilities could be exploited by a remote attacker to run arbitrary code on the targeted system. As per CERT-In, this issue exists in WhatsApp due to the integer overflow, which means that any person can execute remote codes via a video call.

The malicious actor can take control of a user's device by sending a specially-crafted video file, which will let them execute arbitrary code. A hacker can remotely execute commands on someone else's computing device. Usually, remote code executions (RCEs) occur due to malicious malware downloaded by the host. It can happen irrespective of the device's geographic location. The disclosed vulnerability is called CVE-2022-36934 with a severity score of 9.8/10 on the CVE scale.
