Description Kurt Seifried 2015-10-28 15:24:31 EDT
The Samba Project reports:

All versions of Samba from 3.2.0 to 4.3.1 inclusive are vulnerable to
a missing access control check in the vfs_shadow_copy2 module. When
looking for the shadow copy directory under the share path the current
accessing user should have DIRECTORY_LIST access rights in order to
view the current snapshots.

This was not being checked in the affected versions of Samba.
