Few weeks back, well-known hacker and researcher, Ian Beer, from Google’s security-focused Project Zero team had announced plans to release exploits for iOS 11.4.1 – iOS 11.4.
As promised, Ian Beer has released exploits for iOS 11.4 – iOS 11.4.1 titled iOS kernel UaF due to bad error handling in personas, iOS kernel stack memory disclosure due to failure to check copyin return value and iOS/MacOS sandbox escape due to mach message sent from shared memory.
The exploits released by Ian for iOS 11 – iOS 11.1.2 and iOS 11.2 – iOS 11.3.1 (iOS 11.4 beta 4) had been used to develop jailbreak tools for iOS 11 – iOS 11.1.2, and iOS 11.2 – iOS 11.3.1. So not surprisingly, the release of the exploits has sparked off speculations that they could be used to jailbreak iPhone. However, as developer we shouldn’t get too excited as it is still early days. iOS developer Jake James points out that this is still proof of concept.
At the moment, you can only jailbreak iOS 11 – iOS 11.3.1 using Electra jailbreak or Unc0ver jailbreak. It remains to be seen if either coolstar, developer of Electra Jailnbreak or Pwn20wnd, developer of Unc0ver jailbreak will be able to make use of the exploits to develop a jailbreak for iOS 11.4.1 – iOS 11.4.
Have you been eagerly waiting for jailbreak for iOS 11.4.1 or have you already upgraded to iOS 12? Let us know in the comments.
