The remote Ubuntu 22.04 LTS / 23.04 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6426-1 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.
(CVE-2023-39928)
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.
(CVE-2023-41074)
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)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
