The remote Oracle Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2022-1556 advisory.
Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: DML). Supported versions that are affected are 5.7.33 and prior and 8.0.23 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. CVSS 3.1 Base Score 4.9 (Availability impacts). CVSS Vector:
(CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H). (CVE-2021-2166)
Vulnerability in the MySQL Server product of Oracle MySQL (component: InnoDB). Supported versions that are affected are 5.7.34 and prior and 8.0.25 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. CVSS 3.1 Base Score 4.4 (Availability impacts). CVSS Vector:
(CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:N/I:N/A:H). (CVE-2021-2372)
Vulnerability in the MySQL Server product of Oracle MySQL (component: InnoDB). Supported versions that are affected are 5.7.34 and prior and 8.0.25 and prior. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise MySQL Server.

Vulnerability in the MySQL Server product of Oracle MySQL (component: InnoDB). Supported versions that are affected are 5.7.35 and prior and 8.0.26 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 as well as unauthorized update, insert or delete access to some of MySQL Server accessible data. CVSS 3.1 Base Score 5.5 (Integrity and Availability impacts). CVSS Vector:
(CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:L/A:H). (CVE-2021-35604)
MariaDB before 10.6.2 allows an application crash because of mishandling of a pushdown from a HAVING clause to a WHERE clause. (CVE-2021-46666)
MariaDB before 10.6.5 has a sql_lex.cc integer overflow, leading to an application crash. (CVE-2021-46667)
get_sort_by_table in MariaDB before 10.6.2 allows an application crash via certain subquery uses of ORDER BY. (CVE-2021-46657)
save_window_function_values in MariaDB before 10.6.3 allows an application crash because of incorrect handling of with_window_func=true for a subquery. (CVE-2021-46658)
MariaDB through 10.5.9 allows a set_var.cc application crash via certain uses of an UPDATE statement in conjunction with a nested subquery. (CVE-2021-46662)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
