  - Vulnerability in the MySQL Server product of Oracle MySQL (component: InnoDB). Supported versions that are
    affected are 5.7.27 and prior and 8.0.17 and prior. Difficult to exploit 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-2019-2938)

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Optimizer). Supported
    versions that are affected are 5.6.45 and prior, 5.7.27 and prior and 8.0.17 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 ability to cause a hang
    or frequently repeatable crash (complete DOS) of MySQL Server. (CVE-2019-2974)

  - libmariadb/mariadb_lib.c in MariaDB Connector/C before 3.1.8 does not properly validate the content of an
    OK packet received from a server. NOTE: although mariadb_lib.c was originally based on code shipped for
    MySQL, this issue does not affect any MySQL components supported by Oracle. (CVE-2020-13249)

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: FTS). Supported versions
    that are affected are 5.6.49 and prior, 5.7.31 and prior and 8.0.21 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 ability to cause a hang
    or frequently repeatable crash (complete DOS) of MySQL Server. (CVE-2020-14765)

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: InnoDB). Supported versions that are
    affected are 5.7.31 and prior and 8.0.21 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-2020-14776)

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: FTS). Supported versions
    that are affected are 5.7.31 and prior and 8.0.21 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-2020-14789)

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Locking). Supported versions
    that are affected are 5.6.49 and prior, 5.7.31 and prior and 8.0.21 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-2020-14812)

  - A flaw was found in the mysql-wsrep component of mariadb. Lack of input sanitization in `wsrep_sst_method`
    allows for command injection that can be exploited by a remote attacker to execute arbitrary commands on
    galera cluster nodes. This threatens the system's confidentiality, integrity, and availability. This flaw
    affects mariadb versions before 10.1.47, before 10.2.34, before 10.3.25, before 10.4.15 and before 10.5.6.
    (CVE-2020-15180)

    affected are 5.6.46 and prior, 5.7.28 and prior and 8.0.18 and prior. Difficult to exploit vulnerability
    allows unauthenticated attacker with network access via multiple protocols to compromise MySQL Client.
    Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently
    repeatable crash (complete DOS) of MySQL Client. (CVE-2020-2574)

  - Vulnerability in the MySQL Client product of Oracle MySQL (component: C API). Supported versions that are
    affected are 5.6.47 and prior, 5.7.27 and prior and 8.0.17 and prior. Difficult to exploit vulnerability
    allows low privileged attacker with network access via multiple protocols to compromise MySQL Client.

    crash (complete DOS) of MySQL Server as well as unauthorized update, insert or delete access to some of
    MySQL Server accessible data. (CVE-2020-2760)

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: DML). Supported versions
    that are affected are 5.6.47 and prior, 5.7.29 and prior and 8.0.19 and prior. Easily exploitable
    vulnerability allows low privileged attacker with network access via multiple protocols to compromise
