Have Apple fixed the exploits used for iOS 7 Jailbreak in iOS 7.1

Over the last month pod2g, being a key member of the evad3rs dismissed rumors that the iOS 7 Jailbreak has been stolen. But as per the movement for the iOS 7 Jailbreak pod2g said that “the jailbreak stuff is moving on, but slowly.” So you may please move slow in updating your iOS 7.x to 7.1 if you feel you want to have the jailbreak.

Developer of the most popular Jailbreak tools Sn0wbreeze, iH8sn0w tweeted that the iOS 7 beta patches “the mobilebackup2 exploit to write to /var via the MediaDomain symlink” when asked f it was safe n upgrading to iOS 7.1

@iH8sn0w What are your thoughts on IOS 7.1 beta 2 ? Worth upgrading ? Will it affect JB ?

Not sure being if this might be a major setback for Jailbreakers, Mean while reddit user phonenixdev explains :

Mobilebackup2 is the system used to generate your user backups, as well as place them back on the phone. But it’s designed for only particular folders in the user directory.

It has been used in years past via path walking (prepending ..’s to walk up the directory tree) to let us put files in other places in the /var partition. I’m guessing that they found they could do something similar by creating symlinks to other places on the /var partition.

Actually, I’m not guessing. I know you could do that because a failbreak I once made used that. :P

P.S. root partition = where the OS is installed; mounted at the base of the filesystem ( / ). /var partition = where the user data is; mounted at /var. When you update your phone, the root partition is overwritten while the var partition stays around. When you restore your phone, both partitions are wiped.

Stefan Esser, aka i0n1c, believes that the vulnerabilities that was being used for the iOS 7 Jailbreak was being fixed by Apple.

So Apple has killed some vulnerabilities jailbreakers were using for iOS 7 in iOS 7.1 :P

Not being clear if the exploit being used up by the evad3rs in developing the iOS 7 jailbreak, so all we need to do is just to wait until they confirm it.

So if you are waiting for the iOS 7 Jailbreak then you should not upgrade to iOS 7.1 even iOS 7.1 beta that was being released for the developers.

If the Apple had fixed the vulnerabilities that was one part of the progress of the iOS 7 Jailbreak then this might change the meaning that the evad3rs must have to release the Jailbreak for the iOS 7 to iOS 7.0.4. As we thought about that the evad3rs might hold off releasing the Jailbreak until the iOS 7.1 has been released, meanwhile f the vulnerabilities are fixed, unless they find another way in exploit to jailbreak iOS 7.1
