A vulnerability was found in Samba from version (including) 4.9 to versions
before 4.9.6 and 4.10.2. During the creation of a new Samba AD DC, files
are created in a private subdirectory of the install location. This
directory is typically mode 0700, that is owner (root) only access. However
in some upgraded installations it will have other permissions, such as
0755, because this was the default before Samba 4.8. Within this directory,
files are created with mode 0666, which is world-writable, including a
sample krb5.conf, and the list of DNS names and servicePrincipalName values
to update.
