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: DDL). Supported versions     that are affected are 8.4.3 and prior and 9.1.0 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-2025-21499)

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

The versions of MySQL Server installed on the remote host are affected by multiple vulnerabilities as referenced in the January 2025 CPU advisory.
