The remote Fedora 39 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2023-8f84dc8e09 advisory.
The issue was addressed with improved memory handling. This issue is fixed in macOS Sonoma 14.1, Safari 17.1, iOS 16.7.2 and iPadOS 16.7.2, iOS 17.1 and iPadOS 17.1. Processing web content may lead to a denial- of-service. (CVE-2023-41983)
A logic issue was addressed with improved checks. This issue is fixed in iOS 17.1 and iPadOS 17.1, watchOS 10.1, iOS 16.7.2 and iPadOS 16.7.2, macOS Sonoma 14.1, Safari 17.1, tvOS 17.1. Processing web content may lead to arbitrary code execution. (CVE-2023-42852)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
