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

  - A null pointer dereference flaw was found in samba's     Winbind service in versions before 4.11.15, before     4.12.9 and before 4.13.1. A local user could use this     flaw to crash the winbind service causing denial of     service.(CVE-2020-14323,CVE-2020-14318)

  - An elevation of privilege vulnerability exists when an     attacker establishes a vulnerable Netlogon secure     channel connection to a domain controller, using the     Netlogon Remote Protocol (MS-NRPC), aka 'Netlogon     Elevation of Privilege Vulnerability'.(CVE-2020-1472)

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.

  - A flaw was found in the way samba handled file and     directory permissions. An authenticated user could use     this flaw to gain access to certain file and directory     information which otherwise would be unavailable to the     attacker.(CVE-2020-14318)

  - A use-after-free flaw was found in all samba LDAP     server versions before 4.10.17, before 4.11.11, before     4.12.4 used in a AC DC configuration. A Samba LDAP user     could use this flaw to crash samba.(CVE-2020-10760)

  - A NULL pointer dereference, or possible use-after-free     flaw was found in Samba AD LDAP server in versions     before 4.10.17, before 4.11.11 and before 4.12.4.
    Although some versions of Samba shipped with Red Hat     Enterprise Linux do not support Samba in AD mode, the     affected code is shipped with the libldb package. This     flaw allows an authenticated user to possibly trigger a     use-after-free or NULL pointer dereference. The highest     threat from this vulnerability is to system     availability.(CVE-2020-10730)

  - A flaw was found in samba's DNS server. An     authenticated user could use this flaw to the RPC     server to crash. This RPC server, which also serves     protocols other than dnsserver, will be restarted after     a short delay, but it is easy for an authenticated non     administrative attacker to crash it again as soon as it     returns. The Samba DNS server itself will continue to     operate, but many RPC services will     not.(CVE-2020-14383)

  - As Samba internally opens an underlying file system     handle on a directory when a client requests an open,     even for FILE_READ_ATTRIBUTES then if the underlying     file system permissions don&#39t allow &quotr&quot     (read) access for the connected user, then the handle     open request will be denied.&quot(CVE-2020-14318)

The remote CentOS Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the CESA-2021:1647 advisory.

  - samba: Missing handle permissions check in SMB1/2/3 ChangeNotify (CVE-2020-14318)

  - samba: Unprivileged user can crash winbind (CVE-2020-14323)

  - samba: Netlogon elevation of privilege vulnerability (Zerologon) (CVE-2020-1472)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

  - A flaw was found in all Samba versions before 4.10.17,     before 4.11.11 and before 4.12.4 in the way it     processed NetBios over TCP/IP. This flaw allows a     remote attacker could to cause the Samba server to     consume excessive CPU use, resulting in a denial of     service. This highest threat from this vulnerability is     to system availability. (CVE-2020-10745)

  - A use-after-free flaw was found in all samba LDAP     server versions before 4.10.17, before 4.11.11, before     4.12.4 used in a AC DC configuration. A Samba LDAP user     could use this flaw to crash samba. (CVE-2020-10760)
