The version of webkitgtk4 installed on the remote host is prior to 2.42.5-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2024-2623 advisory.

A use-after-free issue was addressed with improved memory management. This issue is fixed in iOS 16.7.9     and iPadOS 16.7.9, Safari 17.6, iOS 17.6 and iPadOS 17.6, watchOS 10.6, tvOS 17.6, visionOS 1.3, macOS     Sonoma 14.6. Processing maliciously crafted web content may lead to an unexpected process crash.
