"According to the versions of the mariadb packages installed, the
EulerOS Virtualization for ARM 64 installation on the remote host is
affected by the following vulnerabilities :

  - The mariadb-libs package provides the essential shared
    libraries for any MariaDB/MySQL client program or
    interface. You will need to install this package to use
    any other MariaDB package or any clients that need to
    connect to a MariaDB/MySQL server. MariaDB is a
    community developed branch of MySQL.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)Vulnerability in the MySQL
    Server product of Oracle MySQL (component: Server:
    Optimizer). Supported versions that are affected are
    5.6.45 and prior, 5.7.27 and prior and 8.0.17 and
    prior. Easily exploitable vulnerability allows low
    privileged attacker with network access via multiple
    protocols to compromise MySQL Server. Successful
    attacks of this vulnerability can result in
    unauthorized ability to cause a hang or frequently
    repeatable crash (complete DOS) of MySQL Server. CVSS
    3.0 Base Score 6.5 (Availability impacts).
    (CVE-2019-2974)Vulnerability in the MySQL Server
    component of Oracle MySQL (subcomponent: Server:
    Optimizer). Supported versions that are affected are
    5.6.42 and prior, 5.7.24 and prior and 8.0.13 and
    prior. Easily exploitable vulnerability allows high
    privileged attacker with network access via multiple
    protocols to compromise MySQL Server. Successful
    attacks of this vulnerability can result in
    unauthorized ability to cause a hang or frequently
    repeatable crash (complete DOS) of MySQL Server. CVSS
    3.0 Base Score 4.9 (Availability impacts).
    (CVE-2019-2481)Vulnerability in the MySQL Server
    component of Oracle MySQL (subcomponent: Server:
    Parser). Supported versions that are affected are
    5.6.42 and prior, 5.7.24 and prior and 8.0.13 and
    prior. Easily exploitable vulnerability allows low
    privileged attacker with network access via multiple
    protocols to compromise MySQL Server. Successful
    attacks of this vulnerability can result in
    unauthorized ability to cause a hang or frequently
    repeatable crash (complete DOS) of MySQL Server. CVSS
    3.0 Base Score 6.5 (Availability impacts).
