According to the version of the samba packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerability :

  - Samba 4.9.x before 4.9.9 and 4.10.x before 4.10.5 has a     NULL pointer dereference, leading to Denial of Service.
    This is related to the AD DC DNS management server     (dnsserver) RPC server process.(CVE-2019-12435)

    This is related to the AD DC DNS management server     (dnsserver) RPC server process.(CVE-2019-12435)

  - A flaw was found in the way samba implemented an RPC     endpoint emulating the Windows registry service API. An     unprivileged attacker could use this flaw to create a     new registry hive file anywhere they have unix     permissions which could lead to creation of a new file     in the Samba share.(CVE-2019-3880)
