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

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Connection Handling).
    Supported versions that are affected are 5.7.40 and prior and 8.0.31 and prior. Easily exploitable     vulnerability allows high privileged attacker with network access via multiple protocols to compromise     MySQL Server.

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

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 f504a8d2-e105-11ed-85f6-84a93843eb75 advisory.
