Samba 4.x < 4.0.21 / 4.1.11 nmbd Remote Code Execution

high Nessus Plugin ID 76973
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote Samba server is affected by a remote code execution vulnerability.


According to its banner, the version of Samba on the remote host is 4.x prior to 4.0.21 / 4.1.11. It is, therefore, affected by a flaw in the NetBIOS name services daemon (nmbd). This flaw may allow an attacker to execute arbitrary code as the superuser.

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


Install the patch referenced in the project's advisory or upgrade to 4.0.21 / 4.1.11 or later.
