Apple shuts down iOS 10.3.2 to verify that the above version of the activation channel cannot be downgraded.

Developers said earlier this month that a jailbreak in iOS 10.3.2 was possible, thanks to a libxpc vulnerability discovered by Google Project Zero team Ian Beer. So have you decided to stay at version 10.3.2 and wait for a jailbreak? If you have upgraded to version 10.3.3, I'm sorry to tell you that you can't be downgraded from today. Apple has turned off the authentication activation channel for iOS 10.3.2.

It is reported that the exposed libxpc vulnerability can elevate the right to gain the highest privileges of the system and thus execute arbitrary code. However, the vulnerability has been fixed in version 10.3.3 of iOS, which means that only if you stay at version 10.3.2 can you wait for the jailbreak procedure to be announced.

IOS 10.3.3 was officially released on July 19 this year, and a total of 47 security vulnerabilities have been fixed, of which the most noteworthy is that this update fixes a serious WiFi vulnerability (CVE-2017-7047), so if you don't want to be hacked to control your iPhone remotely, you'd better update to iOS 10.3.3. This vulnerability will affect iPhone 5 and later devices, iPad 4 and later devices, and iPodtouch 6.
