In July 2021, Apple released iOS 14.7, and the security notes mention:
- Identity Service
- Available for: iPhone 6s and later, iPad Pro (all models), iPad Air 2 and later, iPad 5th generation and later, iPad mini 4 and later, and iPod touch (7th generation)
- Impact: A malicious application may be able to bypass code signing checks
- Description: An issue in code signature validation was addressed with improved checks.
- CVE-2021-30773: Linus Henze (pinauten.de)
Diffing 14.6 and 14.7 shows no changes in IDS frameworks,
and the only change in the identityservicesd daemon is in
IDSIDStatusQueryController, methods _loadCache and _saveCache.
This seems unlikely to be related to "code signature validation".
It turns out the bug is only present in arm64e, which is why diffing arm64 binaries didn't find anything...
