  - A memory corruption issue was addressed with improved state management. This issue is fixed in Safari
    16.4, iOS 16.4 and iPadOS 16.4, macOS Ventura 13.3, iOS 15.7.7 and iPadOS 15.7.7. Processing web content
    may lead to arbitrary code execution. Apple is aware of a report that this issue may have been actively
    exploited against versions of iOS released before iOS 15.7. (CVE-2023-32435)

  - A type confusion issue was addressed with improved checks. This issue is fixed in iOS 16.5.1 and iPadOS
    16.5.1, Safari 16.5.1, macOS Ventura 13.4.1, iOS 15.7.7 and iPadOS 15.7.7. Processing maliciously crafted
