  - 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. 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 5.9 (Availability impacts). CVSS Vector:
    (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H). (CVE-2021-2389)

  - 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
