In addition to security fixes, the updated packages contain bug fixes,
new features, and possibly incompatible changes.

including three of the top vulnerabilities below, as noted in the
April 2019 Critical Patch Update advisory:

  - An unspecified vulnerability in MySQL in the
    'Server : Pluggable Auth' subcomponent could allow an
    unauthenticated attacker to gain complete access to all
    MySQL Server accessible data. (CVE-2019-2632)

  - An unspecified vulnerability in the
    'Server: Compiling (OpenSSL)' subcomponent could allow
    an unauthenticated attacker to gain complete access to
    all MySQL Server accessible data. (CVE-2019-1559)

  - An unspecified vulnerability in the 'InnoDB'
    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-2019-2628)

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