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 :

  - 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)

  - 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)

  - 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)

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.

(CVE-2020-10730)

  - 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)

  - A flaw was found in the AD DC NBT server in all Samba     versions before 4.10.17, before 4.11.11 and before     4.12.4. A samba user could send an empty UDP packet to     cause the samba server to crash. (CVE-2020-14303)

  - 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)
