Do not Update to iOS 7.1 – Apple may have Fixed iOS 7 Exploits
Evad3rs is taking its time to bestow us with iOS 7 jailbreak. Meanwhile, reports go that Apple may have fixed iOS 7 exploits with the latest iOS 7.1 release. Earlier, reports of Evad3rs’ iOS 7 jailbreak being stolen was going rounds. A key member of evad3s namely pod2g dismissed any such claims though. pod2g also shared that the “the jailbreak stuff is moving on, but slowly.”
According to a few tweets, Apple may have fixed iOS 7 exploits with the iOS 7.1 upgrade. iH8sn0w, developer of popular jailbreak tools such as Sn0wbreeze, tweeted
“[iOS] 7.1 does patch the mobilebackup2 exploit to write to /var via the MediaDomain symlink…”
Stefan Esser (i0n1c) who was the hero of “Stolen iOS 7 jailbreak” fiasco tweeted;
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.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.”
If Apple fixed iOS 7 exploits or not, it is not definite. However, if you are looking forward to iOS 7 jailbreak, better to not upgrade to iOS 7.1 upgrade.
