The version of webkitgtk4 installed on the remote host is prior to 2.42.4-3. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2024-2425 advisory.

  • The issue was addressed with improved memory handling. This issue is fixed in Safari 17.2, macOS Sonoma 14.2, iOS 17.2 and iPadOS 17.2, watchOS 10.2, tvOS 17.2, iOS 16.7.3 and iPadOS 16.7.3. Processing an image may lead to a denial-of-service. (CVE-2023-42883)

  • The issue was addressed with improved memory handling. This issue is fixed in Safari 17.2, macOS Sonoma 14.2, watchOS 10.2, iOS 17.2 and iPadOS 17.2, tvOS 17.2. Processing web content may lead to arbitrary code execution. (CVE-2023-42890)

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