iOS 17.7.1 Update for iPhone Changelog
According to Apple, the iOS 17.7.1 update is only available for iPhone models which have not been upgraded to iOS 18 or the latest iOS 18.1 software. It fixes a vulnerability titled CVE-2024-44239, which, Apple says could risk an app being able to leak sensitive kernel state. It is reported to be an information disclosure issue which has since been addressed with improved private data redaction for log entries.
Furthermore, CVE-2024-44269 posed a risk of allowing a malicious app to use shortcuts to access restricted files due to a logic issue. An information disclosure issue was also reported in Siri due to which a sandboxed app could be able to access sensitive user data in system logs. In WebKit, processing maliciously crafted web content could have prevented the Content Security Policy from being enforced. The update fixes all of these issues.
