  - Vulnerability in the MySQL Connectors product of Oracle MySQL (component: Connector/J). Supported versions
    that are affected are 8.0.14 and prior and 5.1.48 and prior. Difficult to exploit vulnerability allows
    unauthenticated attacker with network access via multiple protocols to compromise MySQL Connectors.
    Successful attacks require human interaction from a person other than the attacker and while the
    vulnerability is in MySQL Connectors, attacks may significantly impact additional products. Successful
    attacks of this vulnerability can result in unauthorized update, insert or delete access to some of MySQL
    Connectors accessible data as well as unauthorized read access to a subset of MySQL Connectors accessible
    data. CVSS 3.0 Base Score 4.7 (Confidentiality and Integrity impacts). CVSS Vector:
    (CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:C/C:L/I:L/A:N). (CVE-2020-2875)

  - Vulnerability in the MySQL Connectors product of Oracle MySQL (component: Connector/J). Supported versions
    that are affected are 5.1.48 and prior. Difficult to exploit vulnerability allows high privileged attacker
    with network access via multiple protocols to compromise MySQL Connectors. Successful attacks of this
    vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of
    MySQL Connectors. CVSS 3.0 Base Score 2.2 (Availability impacts). CVSS Vector:
    (CVSS:3.0/AV:N/AC:H/PR:H/UI:N/S:U/C:N/I:N/A:L). (CVE-2020-2933)

    that are affected are 8.0.19 and prior and 5.1.48 and prior. Difficult to exploit vulnerability allows
    unauthenticated attacker with network access via multiple protocols to compromise MySQL Connectors.
    Successful attacks require human interaction from a person other than the attacker. Successful attacks of
    this vulnerability can result in unauthorized update, insert or delete access to some of MySQL Connectors
    accessible data as well as unauthorized read access to a subset of MySQL Connectors accessible data and
