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.
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.”
