Samba 4.0.1 Security Release Available for Download

Release Announcements
---------------------

This is a security release in order to address CVE-2013-0172.

o  CVE-2013-0172:
   Samba 4.0.0 as an AD DC may provide authenticated users with write access
   to LDAP directory objects.

   In AD, Access Control Entries can be assigned based on the objectClass
   of the object.  If a user or a group the user is a member of has any
   access based on the objectClass, then that user has write access to that
   object.

   Additionally, if a user has write access to any attribute on the object,
   they may have access to write to all attributes.

   An important mitigation is that anonymous access is totally disabled by
   default.  The second important mitigation is that normal users are
   typically only given the problematic per-objectClass right via the
   "pre-windows 2000 compatible access" group, and Samba 4.0.0
incorrectly
   does not make "authenticated users" part of this group.

Changes since 4.0.0:
