Some previous WhatsApp versions are insecure, fix them now

WhatsApp

The WhatsApp team has fixed a critical security flaw that may have been used by bad actors to remotely execute malicious code on target endpoints.

WhatsApp for Android before to v2.22.16.12, WhatsApp Business for Android prior to v2.22.16.12, iOS prior to v2.22.16.12, and WhatsApp Business for iOS prior to v2.22.16.12 are all affected by an integer overflow issue.

The flaw, identified as CVE-2022-36934, has a severity rating of 9.8 and is therefore considered “critical.”

Revised information

The vulnerability, as reported by The Verge, permits remote malware execution via a specially setup video connection. If the harmful code ran, viruses or personal information may be taken.

Mobile app users whose apps don’t automatically update should do so as soon as feasible.

Another vulnerability with similar potential and implementation was patched by WhatsApp in the same update. Threat actors could exploit CVE-2022-27492 by delivering a specially prepared video file. This flaw is less severe than the previous (7.8) but still regarded “critical.”

WhatsApp has made numerous key interface upgrades, in addition to security patches.

The company unveiled a new version of its Windows software in August 2022 that could run without a user’s smartphone.

The previous WhatsApp client for Windows 11 (and 10) was a web-based (Electron) effort, but the new programme – which has graduated from beta to its entire release – is a native client that works independently of your smartphone.
