[Announce] Samba 4.1.6, 4.0.16 and 3.6.23 Security Releases Available

[Karolin Seeger]

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

Samba 4.1.6, 4.0.16 and 3.6.23 have been issued as security releases in order
to address CVE-2013-4496 (Password lockout not enforced for SAMR password
changes) and CVE-2013-6442 (smbcacls can remove a file or directory ACL by
mistake). Please note that Samba 3.6.23 is not affected by CVE-2013-6442.

o  CVE-2013-4496:
   Samba versions 3.4.0 and above allow the administrator to implement
   locking out Samba accounts after a number of bad password attempts.

   However, all released versions of Samba did not implement this check for
   password changes, such as are available over multiple SAMR and RAP
   interfaces, allowing password guessing attacks.

   For more details, please refer to
   http://www.samba.org/samba/security/CVE-2013-4496.

o  CVE-2013-6442:
   Samba versions 4.0.0 and above have a flaw in the smbcacls command. If
   smbcacls is used with the "-C|--chown name" or "-G|--chgrp name"
   command options it will remove the existing ACL on the object being
   modified, leaving the file or directory unprotected.

   For more details, please refer to
   http://www.samba.org/samba/security/CVE-2013-6442.
