Today, Apple released a handful of updates, including ones for the iPhone, iPad, Apple Watch, and more. Jailbreakers should take note as all of these updates had a similar theme — uncOver. All of the updates released today, including iOS 13.5.1, iPadOS 13.5.1, tvOS 13.4.6, watchOS 6.2.6, and macOS Catalina 10.15.5 addressed this exploit.
iOS and iPadOS 13.5.1
Light on features, but heavy on the security side, the iOS and iPad 13.5.1 rollout are solely focused on patching the exploit unc0ver used in its recently released jailbreak utility.
“Description: A memory consumption issue was addressed with improved memory handling. CVE-2020-9859: unc0ver”Apple release notes for iOS 13.5.1, iPadOS 13.5.1, tvOS 13.4.6, watchOS 6.2.6 and macOS Catalina 10.15.5
The jailbreak stood out because of the number of devices vulnerable to the exploit. Instead of one device or one version of iOS, the unc0ver exploit worked on all devices running iOS 11 through iOS 13.5. It also worked on tvOS 13.4.
Advice to Jailbreakers
Jailbreakers should not update to iOS 13.5.1 or tVOS 13.4.6. It patches both iOS and tvOS and unjailbreaks your phone, confirms Max Weinbach and uncOver team member Pwn20wnd.
Those who are on iOS 13.5 should stay there to save their jailbreak. Those who have not yet updated to iOS 13.5 and want to do so can still update manually because Apple is still signing this version of iOS.
They will need to use their computer to download and manually install the iOS 13.5 IPSW file. This signing won’t last indefinitely, so people should update immediately. Once the iOS 13.5 update is installed, users then can save their blobs. Do not install iOS 13.5.1.
How to Turn off Automatic Updates
If you want to keep your jailbreak, you’ll need to prevent Apple from installing iOS 13.5.1 automatically on your iPhone or iPad. The toggle to turn off automatic updates is found in the Settings app.
- Open the Settings app and tap iTunes & App Store.
- Scroll until you see Automatic Downloads.
- Set the Updates slider to the off position. For reference, white is off, and green is on.
Once automatic updates are off, you will have to approve each update before it’s installed. These “install update” alerts can pop up frequently, so be prepared to respond “no” to them on a regular basis.
The Apple TV also allows for automatic updates. This feature also can be turned off in the Settings > System > Software Updates menu.
