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: Optimizer). Supported     versions that are affected are 8.0.21 and prior. Easily exploitable vulnerability allows high privileged     attacker with network access via multiple protocols to compromise MySQL Server. Successful attacks of this     vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete     DOS) of MySQL Server. (CVE-2020-14888)

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