  - 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 Client product of Oracle MySQL (component: C API). Supported versions that are
    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.
    Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently
    repeatable crash (complete DOS) of MySQL Client. (CVE-2020-2752)

  - Vulnerability in the MySQL Client product of Oracle MySQL (component: C API). Supported versions that are
    affected are 5.6.47 and prior, 5.7.29 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 read access to a subset of MySQL
    Client accessible data. (CVE-2020-2922)

  - Vulnerability in the MySQL Client product of Oracle MySQL (component: C API). Supported versions that are
    affected are 5.6.47 and prior, 5.7.29 and prior and 8.0.19 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 read access to a subset of MySQL
    Client accessible data. (CVE-2021-2007)

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