The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2020:5503 advisory.

  - 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 number.
