  - In SQLite through 3.31.1, the ALTER TABLE implementation has a use-after-free, as demonstrated by an ORDER
    BY clause that belongs to a compound SELECT statement. (CVE-2020-11656)

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: DML). Supported versions
    that are affected are 5.7.30 and prior and 8.0.20 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-2020-14540)

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Information Schema).
    Supported versions that are affected are 5.6.48 and prior, 5.7.30 and prior and 8.0.20 and prior. Easily
    exploitable vulnerability allows low privileged attacker with network access via multiple protocols to
    compromise MySQL Server. Successful attacks of this vulnerability can result in unauthorized read access
    to a subset of MySQL Server accessible data. (CVE-2020-14559)

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: InnoDB). Supported versions that are
    affected are 8.0.20 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 read access to a subset of MySQL Server accessible data. (CVE-2020-14634)

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Security: Roles). Supported
    versions that are affected are 8.0.20 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 access to critical data or complete access to all MySQL Server
    accessible data. (CVE-2020-14641)
