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

  - MariaDB Server v10.6 and below was discovered to contain an use-after-free in the component
    my_strcasecmp_8bit, which is exploited via specially crafted SQL statements. (CVE-2022-27383)

  - MariaDB Server v10.7 and below was discovered to contain a segmentation fault via the component
    sql/sql_class.cc. (CVE-2022-27386)

  - MariaDB Server v10.6.3 and below was discovered to contain an use-after-free in the component
    my_wildcmp_8bit_impl at /strings/ctype-simple.c. (CVE-2022-27455)

  - MariaDB Server v10.6.3 and below was discovered to contain an use-after-free in the component
    my_mb_wc_latin1 at /strings/ctype-latin1.c. (CVE-2022-27457)

  - 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 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.");
