iOS 17.5 Includes These 15 Security Fixes, But One Causes Another Bug

iOS 17.5 and iPadOS 17.5 include 15 security patches for the iPhone and iPad, according to a recently-published Apple support document, but unfortunately one of the patches has led to a software bug affecting alternative app marketplaces.

iOS 17
According to Mysk, a security patch related to the MarketplaceKit framework has resulted in a bug that prevents iPhone users in the EU from reinstalling an alternative app marketplace like AltStore if they happen to delete the app after initially installing it. Apple will likely fix this issue in a subsequent update, such as iOS 17.5.1.

In related news, one security researcher has complained that the iOS kernel vulnerability they discovered was not eligible for payment under the Apple Security Bounty program. It is listed in the iOS 17.5 security fixes below under "AppleAVD."

Who would be positive about a bug that worsens the user experience in an optional system feature?
Some folks on here really don’t want others to have the ability to install whatever they want on their own phones. Like it personally offends them and affects their lives somehow.

I have installed my first AltStore (SetApp Mobile - in beta). Works great. Very intuitive, no dramatic warnings by Apple, everything works as expected.

The only thing is that you get a warning when trying to install the store. You first need to approve this manually in Settings. For each developer.

Otherwise there’s no difference with App Store apps. Curious how smooth app updates will work.
