The remote host is affected by the vulnerability described in GLSA-202105-27 (MySQL: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in MySQL. Please review       the CVE identifiers referenced below for details.
  Impact :

    An attacker could possibly execute arbitrary code with the privileges of       the process, escalate privileges, gain access to critical data or       complete access to all MySQL server accessible data, or cause a Denial of       Service condition.
  Workaround :

    There is no known workaround at this time.

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 8.0.22 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-2021-2021)

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

The remote CentOS Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the CESA-2021:3590 advisory.
