CTOnews.com September 23 message, a new Bug in iOS 16 has been exposed, which can cause the mail application to flicker by sending an email containing a special text string.

The Bug was discovered by Equinux, which discovered this vulnerability in iOS 16 when analyzing spam. According to the company, many people on the team experienced a crash of the iOS email application, which was characterized by a flicker when the app was launched.

After their research, they found that their team all received the same spam email, which at first glance was just a very ordinary HTML email. However, if you look at the title of the email, you can see that the spammers have done something in the "from" column.

Typically, the from field in a message looks like this:

From: sender@example.com.

But the from field of this spam has several extra characters that cause the email application to crash.

According to Equinux, this means that "anyone can send an email to any iOS 16 user that can crash their email application." They created a form field on the site that can be used to test the bug, which they call "Mailjack".

Mailjack can affect mail applications on any device running iOS 16 (stable version), iOS 16.0.1 on iPhone14, and the latest iPadOS 16 beta, but some mail services, including Gmail, Outlook, and Hotmail, rewrite incoming messages to prevent similar things from happening.

In addition, Gmail and Yahoo completely block these malicious emails, but iCloud email does not do so, which is Apple's own email service.

The message may also be classified as the "spam" inbox, and if so, the mail application crashes every time you check the spam inbox, which is better than when the message appears in the main inbox.

Currently, the solution to this problem is to remove the spam from the account on a device that is not running iOS 16 or through a different mail client.

CTOnews.com has learned that Apple has yet to respond to this.
