"The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied
patch available.

  - A flaw was found in pki-core, which could allow a user to get a certificate for another user identity when
    directory-based authentication is enabled. This flaw allows an authenticated attacker on the adjacent
    network to impersonate another user within the scope of the domain, but they would not be able to decrypt
    message content. (CVE-2022-2393)

Note that Nessus relies on the presence of the package as reported by the vendor.");
