The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3183 advisory.

  • The issue was addressed with improved UI handling. This issue is fixed in tvOS 16.1, macOS Ventura 13, watchOS 9.1, Safari 16.1, iOS 16.1 and iPadOS 16. Visiting a malicious website may lead to user interface spoofing. (CVE-2022-42799)

  • A type confusion issue was addressed with improved memory handling. This issue is fixed in tvOS 16.1, macOS Ventura 13, watchOS 9.1, Safari 16.1, iOS 16.1 and iPadOS 16. Processing maliciously crafted web content may lead to arbitrary code execution. (CVE-2022-42823)

  • A logic issue was addressed with improved state management. This issue is fixed in tvOS 16.1, macOS Ventura 13, watchOS 9.1, Safari 16.1, iOS 16.1 and iPadOS 16. Processing maliciously crafted web content may disclose sensitive user information. (CVE-2022-42824)

Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
