dsa-5527 advisory.

  - A use-after-free vulnerability exists in the MediaRecorder API of Webkit WebKitGTK 2.40.5. A specially
    crafted web page can abuse this vulnerability to cause memory corruption and potentially arbitrary code
    execution. A user would need to to visit a malicious webpage to trigger this vulnerability.

  - The issue was addressed with improved checks. This issue is fixed in tvOS 17, Safari 17, watchOS 10, iOS
    17 and iPadOS 17, macOS Sonoma 14. Processing web content may lead to arbitrary code execution.

  - The issue was addressed with improved checks. This issue is fixed in Safari 17, iOS 16.7 and iPadOS 16.7,
    macOS Sonoma 14. 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 before iOS 16.7. (CVE-2023-41993)
