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

  - 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)

  - 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)

This update for samba fixes the following issues :

CVE-2020-14323: Unprivileged user can crash winbind (bsc#1173994).

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

  - 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 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)

The Samba Team reports :

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

- CVE-2020-14323: Unprivileged user can crash winbind

- CVE-2020-14383: An authenticated user can crash the DCE/RPC DNS with easily crafted records

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4611-1 advisory.

    Steven French discovered that Samba incorrectly handled ChangeNotify permissions. A remote attacker could     possibly use this issue to obtain file name information. (CVE-2020-14318)

    Bas Alberts discovered that Samba incorrectly handled certain winbind requests. A remote attacker could     possibly use this issue to cause winbind to crash, resulting in a denial of service. (CVE-2020-14323)

    Francis Brosnan Blzquez discovered that Samba incorrectly handled certain invalid DNS records. A remote     attacker could possibly use this issue to cause the DNS server to crash, resulting in a denial of service.
    (CVE-2020-14383)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

  - 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)

  - 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 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)
