FreeBSD : samba -- ACLs are not checked on opening an alternate data stream on a file or directory (a4f08579-516c-11e3-9b62-000c292e4fd8)

medium Nessus Plugin ID 70966
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.

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The Samba project reports :

Samba versions 3.2.0 and above (all versions of 3.2.x, 3.3.x, 3.4.x, 3.5.x, 3.6.x, 4.0.x and 4.1.x) do not check the underlying file or directory ACL when opening an alternate data stream.

According to the SMB1 and SMB2+ protocols the ACL on an underlying file or directory should control what access is allowed to alternate data streams that are associated with the file or directory.

Solution

Update the affected packages.
