Apple released its new version of iOS, i.e. iOS 6.1.3, yesterday with some fixes to the security bug along with the blockage of Evasi0n untethered jailbreak on all iOS devices including the latest iPhone, iPad and iPod Touch.
So, the people who want to use jailbreaked devices have to stay on the iOS 6.1.2 as iOS 6.1.3 will not allow the Evasi0n to jailbreak the devices and after upgrade to the iOS 6.1.3 users cannot downgrade to the earlier version.
Apple credited the Evasi0n team, known as the evad3rs, for uncovering the four of the security holes that were rectified, in the release note. Overall, Apple fixed six bugs;
- Dyld – the user to execute unsigned code
- Kernel – the user to find the address of structures in the kernel
- Lockdown – the user to change permissions on arbitrary files
- Passcode lock – the user to bypass the screen lock
- USB – the user to execute arbitrary code in the kernel
- WebKit – Visiting a maliciously crafted website may lead to an unexpected application termination or arbitrary code execution
According to Lance Whitney of CNET, “Evasi0n proved to be perhaps the most popular iOS jailbreak ever released. Following its debut in early February, the tool was downloaded almost 7 million times in less than a week.” It managed to work against iOS 6.1.1. and 6.1.2.
