"The version of MySQL running on the remote host is 5.6.x prior to
5.6.45. It is, therefore, affected by multiple vulnerabilities,
including three of the top vulnerabilities below, as noted in the
July 2019 Critical Patch Update advisory:

  - An unspecified vulnerability in the 'Server: XML'
    subcomponent could allow a high privileged attacker to
    cause the server to hang or to, via a frequently
    repeatable crash, cause a complete denial of service.
    (CVE-2019-2740)

  - As unspecified vulnerability in the 'Server: Security:
    Audit' subcomponent could allow an unauthenticated
    attacker to cause the server to hang or to, via a
    frequently repeatable crash, cause a complete denial of
    service. Additionally, a successful attacker could
    perform unauthorized modifications to some MySQL Server
    accessible data. (CVE-2019-2819)

  - As unspecified vulnerability in the 'Server: Security:
    Privileges' subcomponent could allow an unauthenticated
    attacker to cause the server to hang or to, via a
    frequently repeatable crash, cause a complete denial of
    service. Additionally, a successful attacker could
    perform unauthorized modifications to some MySQL Server
    accessible data. (CVE-2019-2739)

Note that Nessus has not tested for these issues but has instead
relied only on the application's self-reported version number.");
