- Facebook says stack-based buffer overflow could be triggered in WhatsApp
- The vulnerability can be exploited to execute DoS or deploy malware
- Hackers can use the WhatsApp flaw to steal files or for surveillance
WhatsApp has been hit by a security flaw, but, it only affects older versions of the app for Android and iPhone. The latest WhatsApp security vulnerability gives hackers a cyber-attack vector. If someone has sent you an MP4 file on WhatsApp, you should guard against downloading it as hackers may use a critical vulnerability in the Facebook-owned app to execute snooping attack on both Android and iOS devices. The specially-crafted MP4 file triggers the remote code execution (RCE) and denial of service (DoS) cyber-attack. Users are recommended to update their WhatsApp app to avoid being targeted.
“The vulnerability is classified as ‘Critical’ severity that affected an unknown code block of the component MP4 File Handler in WhatsApp,” reported gbhackers.com on Saturday.
Facebook has issued an advisory, saying “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.”
