"According to the versions of the mariadb packages installed, the EulerOS installation on the remote host is affected by
the following vulnerabilities :

  - 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 10.5.9 allows a set_var.cc application crash via certain uses of an UPDATE statement in
    conjunction with a nested subquery. (CVE-2021-46662)

  - 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)

advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional
