The version of AHV installed on the remote host is prior to 20201105.30142. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AHV-20201105.30142 advisory.

  - A flaw was found in RPM's signature check functionality when reading a package file. This flaw allows an     attacker who can convince a victim to install a seemingly verifiable package, whose signature header was     modified, to cause RPM database corruption and execute code. The highest threat from this vulnerability is     to data integrity, confidentiality, and system availability. (CVE-2021-20271)

  - The Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) before 1.18.5 and 1.19.x before 1.19.3 has     a NULL pointer dereference in kdc/do_tgs_req.c via a FAST inner body that lacks a server field.
    (CVE-2021-37750)

  - sshd in OpenSSH 6.2 through 8.x before 8.8, when certain non-default configurations are used, allows     privilege escalation because supplemental groups are not initialized as expected. Helper programs for     AuthorizedKeysCommand and AuthorizedPrincipalsCommand may run with privileges associated with group     memberships of the sshd process, if the configuration specifies running the command as a different user.
    (CVE-2021-41617)

  - ** DISPUTED ** An issue was discovered in the Bidirectional Algorithm in the Unicode Specification through     14.0. It permits the visual reordering of characters via control sequences, which can be used to craft     source code that renders different logic than the logical ordering of tokens ingested by compilers and     interpreters. Adversaries can leverage this to encode source code for compilers accepting Unicode such     that targeted vulnerabilities are introduced invisibly to human reviewers. NOTE: the Unicode Consortium     offers the following alternative approach to presenting this concern. An issue is noted in the nature of     international text that can affect applications that implement support for The Unicode Standard and the     Unicode Bidirectional Algorithm (all versions). Due to text display behavior when text includes left-to-     right and right-to-left characters, the visual order of tokens may be different from their logical order.
    Additionally, control characters needed to fully support the requirements of bidirectional text can     further obfuscate the logical order of tokens. Unless mitigated, an adversary could craft source code such     that the ordering of tokens perceived by human reviewers does not match what will be processed by a     compiler/interpreter/etc. The Unicode Consortium has documented this class of vulnerability in its     document, Unicode Technical Report #36, Unicode Security Considerations. The Unicode Consortium also     provides guidance on mitigations for this class of issues in Unicode Technical Standard #39, Unicode     Security Mechanisms, and in Unicode Standard Annex #31, Unicode Identifier and Pattern Syntax. Also, the     BIDI specification allows applications to tailor the implementation in ways that can mitigate misleading     visual reordering in program text; see HL4 in Unicode Standard Annex #9, Unicode Bidirectional Algorithm.
    (CVE-2021-42574)

  - NSS (Network Security Services) versions prior to 3.73 or 3.68.1 ESR are vulnerable to a heap overflow     when handling DER-encoded DSA or RSA-PSS signatures. Applications using NSS for handling signatures     encoded within CMS, S/MIME, PKCS \#7, or PKCS \#12 are likely to be impacted. Applications using NSS for     certificate validation or other TLS, X.509, OCSP or CRL functionality may be impacted, depending on how     they configure NSS. *Note: This vulnerability does NOT impact Mozilla Firefox.* However, email clients and     PDF viewers that use NSS for signature verification, such as Thunderbird, LibreOffice, Evolution and     Evince are believed to be impacted. This vulnerability affects NSS < 3.73 and NSS < 3.68.1.
    (CVE-2021-43527)

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