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

  - MariaDB is a community developed branch of MySQL.
    MariaDB is a multi-user, multi-threaded SQL database
    server. It is a client/server implementation consisting
    of a server daemon (mysqld) and many different client
    programs and libraries. The base package contains the
    standard MariaDB/MySQL client programs and generic
    MySQL files.Security Fix(es):Vulnerability in the MySQL
    Client product of Oracle MySQL (component: C API).
    Supported versions that are affected are 5.6.46 and
    prior, 5.7.28 and prior and 8.0.18 and prior. Difficult
    to exploit vulnerability allows unauthenticated
    attacker with network access via multiple protocols to
    compromise MySQL Client. Successful attacks of this
    vulnerability can result in unauthorized ability to
    cause a hang or frequently repeatable crash (complete
    DOS) of MySQL Client.(CVE-2020-2574)

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.");
