Synopsis

The remote EulerOS host is missing multiple security updates.

Description

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

- A remote code execution issue was discovered in MariaDB 10.2 before 10.2.37, 10.3 before 10.3.28, 10.4 before 10.4.18, and 10.5 before 10.5.9; Percona Server through 2021-03-03; and the wsrep patch through 2021-03-03 for MySQL. An untrusted search path leads to eval injection, in which a database SUPER user can execute OS commands after modifying wsrep_provider and wsrep_notify_cmd. NOTE: this does not affect an Oracle product. (CVE-2021-27928)

- 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 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)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected mariadb packages.
