Descriptions

This was addressed with additional checks by Gatekeeper on files downloaded from an iCloud shared-by-me folder. This issue is fixed in macOS Ventura 13.3, iOS 16.4 and iPadOS 16.4. A file from an iCloud shared-by-me folder may be able to bypass Gatekeeper.

iOS 16.4 and iPadOS 16.4 addresses buffer overflow, bypass, code execution, integer overflow, out of bounds read, out of bounds write, and use-after-free vulnerabilities.
