Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the 5afd64ae-122a-11ef-8eed-1c697a616631 advisory.

- Intel reports: Potential security vulnerabilities in some Intel Trust Domain Extensions (TDX) module software may allow escalation of privilege. Improper input validation in some Intel TDX module software before version 1.5.05.46.698 may allow a privileged user to potentially enable escalation of privilege via local access. Intel is releasing firmware updates to mitigate these potential vulnerabilities. A potential security vulnerability in some Intel Processors may allow information disclosure. Hardware logic contains race conditions in some Intel Processors that may allow an authenticated user to potentially enable partial information disclosure via local access. Intel is releasing microcode updates to mitigate this potential vulnerability. A potential security vulnerability in Intel Core Ultra Processors may allow denial of service. Sequence of processor instructions leads to unexpected behavior in Intel Core Ultra Processors may allow an authenticated user to potentially enable denial of service via local access. Intel is releasing microcode updates to mitigate this potential vulnerability. (CVE-2023-45733, CVE-2023-45745, CVE-2023-46103)

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