During the afternoon yesterday we saw how Apple released the final version of iOS 10.3.3 An update that as we saw is a minor update and focuses on correcting different errors and improving system security. The security of the system is what most solves this version of iOS.
This version caught us a little by surprise, because although Apple already had a few betas, it is normally expected to launch the seventh beta and later the definitive version. This time he had six betas behind him, so something made them move forward. In fact, as some readers have indicated in the comments, I myself indicate that the final version was expected for August and has not been so. There is a compelling reason: iOS 10.3.3 fixes a major security hole.
The bug that resolves version 10.3.3 of Apple’s operating system is known as Broadpwn, a vulnerability in Broadcom’s Wi-Fi chipsets affecting millions of Android and iOS devices. Google released an update “security review” Android on July 5 to solve just this problem affecting models of all manufacturers, from LG to Samsung. Now Apple does the same 15 days later.
The Broadpwn vulnerability was recently discovered by researcher Nitay Artenstein of Exodus Intelligence and will be presented for the first time in detail at the BlackHat 2017 cybersecurity conference, which begins in Las Vegas on July 22. With all the cases of recent cyber attacks, such as those of ranswomare Wannacry or Petya, thanks to outdated systems, now more than ever it is important to give that “update” button.
According to CNET, the Broadcom BCM43xx Wi-Fi chips (which the iPhone carries) contain an exploit that allows hackers to access a device and control it just by being on the same Wi-Fi network. That is, it is enough that the attacker is on the same Wi-Fi network as you to take control of the phone and spoil it, even taking your password or another firewall.
Broadcom Wi-Fi chips as we have indicated are used from the iPhone 5 and iPad 4 forward, including the sixth-generation iPod touch. The solution? Update as soon as possible your iPhone or iPad to iOS 10.3.3 The Apple security document describes it like this:

Impact: An attacker within range may be able to execute arbitrary code on the Wi-Fi chip

Description: A memory corruption issue was addressed with improved memory handling

This exploit not only affected the iPhone and iPad, but also devices HTC, LG or Smasung. Google however has also corrected this security hole with an update on July 5. In short, one more example of the importance of updating our devices always to the latest version.
