Apple Releases iOS and iPadOS 13.5.1 With Fixes for Recent ‘unc0ver’ Jailbreak Vulnerability
Apple has just released iOS and iPadOS 13.5.1 to the public following last month’s release of iOS 13.5 with a set of security updates. The company’s supports page hints that the new update patches the vulnerability used by Unc0ver Team to jailbreak iOS 13.5 devices. The Unc0ver jailbreak was released on May 24 and was the first jailbreaking tool that worked on a current version of iOS.
According to Apple’s official security page, iOS 13.5.1 and iPadOS 13.5.1 fixes a vulnerability that allowed applications to execute arbitrary code with kernel privileges. Apple has also mentioned that the exploit is the same one found recently by Unc0ver Team, which confirms that the latest version of iOS 13 blocks the jailbreak process once again.
Apple is also releasing update watchOS 6.2.6 to the public as well as iPadOS 13.5.1 and updates to HomePod and Apple TV. The updated versions of Apple will be available to all users soon. Once Apple stops signing iOS 13.5, it will be impossible to use the Unc0ver jailbreak until another exploit is found. Also if an iOS user has used the Unc0ver tool to jailbreak his iOS device, installing iOS 13.5.1 will remove it and block the device from jailbreaking.
Jailbreaking an iPhone gives the iOs users root access to the iPhone, allowing them to install apps outside of Apple’s App Store. Jailbreakers in support say that breaking through those restrictions allows them greater customization over their iPhones.
Apple has always been quick at patching the vulnerabilities being exploited by jailbreakers. The Unc0ver jailbreak has been out for only a week and Apple has already patched it. Apple does this to improve device security and to reduce the surface area in which hackers can attack the software.
Unc0ver’s jailbreak tool uses a zero-day kernel exploit and enables system modifications on any Apple device using the iOS 13 version. As per details a kernel exploit is usually different from a hardware exploit and can work on any newer devices to open gates for any apps outside the App Store.
Security experts are against jailbreaking as it exposes an iOS device owner to security threats, and advise the users to install the update on their devices as soon as one is available. As per expert criminals may jailbreak an iPhone to install malware or target jailbroken iPhones.
Apple has always tried to have jailbreak of the devices declared illegal but has not succeeded to do so in the US or other countries. Over jailbreaking concerns, Apple had also said that they may deny service for an iPhone, iPad, or iPod touch that has installed any unauthorized software.
