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.
