  • Pangu Jailbreak Team Details Exploits Found in iOS 8.4.1


    You may recall that last month, the Pangu jailbreak team demonstrated an iOS 8.4.1 jailbreak, but never released it because they were waiting to see what happens with iOS 9, which is currently in its late beta stages and will be released to the public this Fall.

    On Tuesday, the Pangu jailbreak team published a blog post outlining some of the details about what they used to exploit the kernel in iOS 8.4.1. The team notes that the three kernel exploits shared are closed in the iOS 9 beta, which means there's no shame in sharing the exploits with the public now.

    Pangu notes that Apple's code in "com.apple.driver.AppleHDQGasGaugeControl" isn't of very high quality and has been very easy for the team to exploit. One of the exploits even gives the Pangu jailbreak team the ability to gain code execution in the kernel itself; this one is known as a "perfect heap overflow" vulnerability.

    To read the full post about these vulnerabilities, which is surprisingly written in a way that even a non-hacker could understand, you can check out Pangu's blog at this link to learn more.

      Sounds good to me. Has there ever been an iOS update that the Dev's could not JB? I cannot think of one off hand. Let me know..curious.

      So far, it's never been a matter of if they could do it or not, as much as it being a matter of if they wanted to or not. A lot of times, they just pushed the jailbreak off until a newer release.

      I wonder how iOS 9 will fare with its "rootless" feature.

      Got to have faith brother, that the teams will find a way to jailbreak. Fingers crossed...

      I think that, more than revenue protection, this is why Apple doesn't provide the ease of installing things outside of the App Store... if Apple allowed adding "non-approved" apps and tweaks outside of the app store without the need to jailbreak, they'd lose a massive amount of free community security / vulnerability testing that they then use to make their OS even more secure. They're really expertly taking advantage of the jailbreak community.

      I don't see there being much difficulty in jailbreaking iOS 9 once it comes out. This rootless thing has been blown a little out of proportion IMO.

      iOS9 make take longer to JB, but just like every other, it will be hacked!

      i completely agree with you.. yes, something new may cause new challenges, but we all will be JB on ios 9 before the end of the year probably .

      I think because of a new "rootless" feature, more teams will try to hack iOS 9. Even the folks that stopped, not because they couldn't do it but because it got boring for them. We need a new jailbreakme.com and then millions of videos of people jailbreaking inside Apple stores.

      Correct me if I'm wrong but the last jailbreak that ran as root was evasion7 in 2013? Last few jailbreaks haven't run initially as root, so I don't think rootless will be a huge issue. It's more the kernal patch protection that I feel will hurt the jail breaking efforts. KPP is where the kernal periodically checks it's own integrity and panics if it detects a modification, so doesn't take a genius to figure out that that may be an issue!

      I wish they would turn their attention to jailbraking my Apple TV 3.

      Fire TV Stick with Kodi is the way to go now IMO.

      With the exploits being closed why don't they jailbreak 8.4.1 so at least all version of 8 are jail breakable ?

      How is Kodi different than Plex? I know I can google but thought you might be able to tell me in one sentence. Also, a good link to installation would be helpful if I decide to go that route. Pretty happy with Plex as of now.

      Plex is based off of Kodi (xbmc) originally. Was made easier to use, polished up quite a bit UI wise then grew into what it is now.
