Developer Publishes iOS 12.0 - 12.1 Safari Sandbox Escape That Can Produce an iOS 12 Jailbreak
In recent weeks, there have been multiple attempts to produce an exploit for the iOS 12 jailbreak, but none of them has seen the light of day although one known security researcher who goes by the name of @SorryMyBad on Twitter will reportedly release an exploit soon. Now, a recent activity suggested that the exploit has been developed continuously, making people in the jailbreak community to be more hopeful that the result would be positive.
Recently, a new powerful iOS/macOS Safari sandbox escape was published, which affects iOS 12.0 through iOS 12.1, as per Redmond Pie. This activity pushed many users that it will finally give way to the iOS 12 jailbreak anytime soon despite many uncertainties, and people are already desperate.
Twitter users even begged security researcher @SorryMyBad to save the jailbreak community after many unsuccessful attempts from many known developers and security researchers. The latest detail that was published is an iOS and macOS Safari sandbox escape through a heap overflow bug in Apple's QuartzCore framework.
The aforementioned framework is responsible for validating the classes and supporting elements such as signatures for the Core Animation functionality as well as Apple's methods in its network. Further, the framework also holds APIs (Application Program Interface) and information in relation to the Core Image.
It is said that a function in the QuartzCore framework "does not notice the case of integer overflow," and this is why the recently published iOS/macOS Safari sandbox escape became a success alongside a documented exploit. Many users also speculated that the recent activity is related to the Pangu Team IOHID vulnerability that was published previously, which will eventually lead to an iOS 12.0 to iOS 12.1 jailbreak in the near future.
There have been a lot of developers and security researchers who tried to produce an exploit to liberate a stock iOS 12 device but the latest movement is relatively positive. However, users may have to wait for a little while as one developer @pwn20wnd suggested on Reddit that this undertaking might take another 3 - 6 months to finally achieve a jailbreak exploit, especially that the Pangu Team's work has not been considered successful in resolving the jailbreak yearning of many users.
The recent work published definitely gives hope to all iOS users, apart from @S0rryMyBad's recent attempts to produce an iOS 12 jailbreak exploit. His work is expected to be the most reliable thus far, which can be directly used in a jailbreak.
For now, users may have to wait for a final and successful iOS 12 jailbreak, but everything is positive.
