"According to its self-reported version, the Tenable Nessus Agent running on the remote host is 10.4.2. It is,
therefore, affected by multiple vulnerabilities as referenced in the TNS-2023-38 advisory.

  - Nessus Agent leverages third-party software to help provide underlying functionality. Several of the
    third-party components (OpenSSL, zlib) were found to contain vulnerabilities, and updated versions have
    been made available by the providers.Out of caution and in line with best practice, Tenable has opted to
    upgrade these components to address the potential impact of the issues. Nessus Agent 10.4.3 updates
    OpenSSL to version 3.0.12 and zlib fixes have been applied to address the identified
    vulnerabilities.Additionally, one other vulnerability was discovered, reported and fixed:Under certain
    conditions, a low privileged attacker could load a specially crafted file during installation or upgrade
    to escalate privileges on Windows and Linux hosts. - CVE-2023-5847 Tenable has released Nessus Agent
    10.4.3 to address these issues. The installation files can be obtained from the Tenable Downloads Portal
    (https://www.tenable.com/downloads/nessus-agents). (CVE-2023-3446, CVE-2023-3817, CVE-2023-45853,
    CVE-2023-4807, CVE-2023-5847)

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