"The version of mariadb installed on the remote host is prior to 5.5.68-1. It is, therefore, affected by multiple
vulnerabilities as referenced in the ALAS2-2023-2057 advisory.

  - get_sort_by_table in MariaDB before 10.6.2 allows an application crash via certain subquery uses of ORDER
    BY. (CVE-2021-46657)

  - MariaDB before 10.7.2 allows an application crash because it does not recognize that
    SELECT_LEX::nest_level is local to each VIEW. (CVE-2021-46659)

  - MariaDB through 10.5.9 allows an application crash in find_field_in_tables and find_order_in_list via an
    unused common table expression (CTE). (CVE-2021-46661)

  - MariaDB through 10.5.13 allows a ha_maria::extra application crash via certain SELECT statements.
    (CVE-2021-46663)

  - 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)

  - MariaDB through 10.5.9 allows an application crash via certain long SELECT DISTINCT statements that
    improperly interact with storage-engine resource limitations for temporary data structures.
    (CVE-2021-46668)

  - An issue in the component my_decimal::operator= of MariaDB Server v10.6.3 and below was discovered to
    allow attackers to cause a Denial of Service (DoS) via specially crafted SQL statements. (CVE-2022-27380)

  - An issue in the component Item_subselect::init_expr_cache_tracker of MariaDB Server v10.6 and below was
    discovered to allow attackers to cause a Denial of Service (DoS) via specially crafted SQL statements.
    (CVE-2022-27384)

  - MariaDB Server before 10.7 is vulnerable to Denial of Service. While executing the
    plugin/server_audit/server_audit.c method log_statement_ex, the held lock lock_bigbuffer is not released
    correctly, which allows local users to trigger a denial of service due to the deadlock. (CVE-2022-31624)

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