WhatsApp has patched two critical vulnerabilities that could possibly be exploited for distant code execution.

WhatsApp solely has three safety advisories for 2022, with the primary two launched in January and February. The newest advisory, launched this month, informs prospects of two memory-related points affecting the WhatsApp cellular purposes.

One of many flaws, tracked as CVE-2022-36934 and rated ‘essential’, is an integer overflow concern that impacts WhatsApp for Android previous to 2.22.16.12, Enterprise for Android previous to 2.22.16.12, iOS previous to 2.22.16.12, and Enterprise for iOS previous to 2.22.16.12.

In line with WhatsApp, an attacker can exploit the vulnerability for distant code execution throughout a video name.

The second concern, a high-severity flaw tracked as CVE-2022-27492, is an integer underflow that may be exploited for distant code execution by sending a specifically crafted video file to the focused consumer. It has been patched in WhatsApp for Android and iOS with the discharge of variations 2.22.16.2 and a pair of.22.15.9, respectively.

In line with cybersecurity agency Malwarebytes, CVE-2022-36934 impacts the Video Name Handler part, whereas CVE-2022-27492 impacts the Video File Handler part.

The vulnerabilities seem to have been found internally and there’s no indication that they’ve been exploited within the wild.

WhatsApp vulnerabilities could be extremely beneficial to malicious actors. There have been reviews in recent times of WhatsApp zero-days being exploited to put in malware on smartphones. WhatsApp has even filed a lawsuit in opposition to Israeli spy ware firm NSO Group for infecting prospects’ telephones.

Exploit acquisition firm Zerodium is at present providing as much as $1 million for WhatsApp exploits that obtain distant code execution and native privilege escalation, and as much as $1.5 million if the exploit doesn’t require any consumer interplay.
