For the iOS sandbox.
Jonathan Levin, a security researcher and trainer specializing in iOS, said: “Since iOS 12.4 is the latest version of iOS available, it is the only version that Apple is allowed to upgrade in the next few days. (until release 12.4.1), all devices running this version of the system (or any version below 12.3) are hackable. This means that they are also vulnerable to exploits that have actually been exposed for more than 100 days.” /p>
Given that Apple was notified of this vulnerability by Google’s Project Zero team more than 100 days ago, people who are unfriendly to Apple’s user security system are likely to be aware of this issue and may use it quietly in the background. Also, if the user is using iOS 12.3, please don’t upgrade to iOS 12.4 to be protected in the next few days. (Tencent Technology Review / Jinlu)
