Samba 4.1.1 Available for Download

                   Release Notes for Samba 4.1.1
                         November 11, 2013

This is a security release in order to address
CVE-2013-4475 (ACLs are not checked on opening an alternate
data stream on a file or directory) and
CVE-2013-4476 (Private key in key.pem world readable).

o  CVE-2013-4475:
   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.

   By default no version of Samba supports alternate data streams
   on files or directories.

   Samba can be configured to support alternate data streams by loading
   either one of two virtual file system modues (VFS) vfs_streams_depot or
   vfs_streams_xattr supplied with Samba, so this bug only affects Samba
   servers configured this way.

   To determine if your server is vulnerable, check for the strings
   "streams_depot" or "streams_xattr" inside your smb.conf configuration

o  CVE-2013-4476:
   In setups which provide ldap(s) and/or https services, the private
   key for SSL/TLS encryption might be world readable. This typically
   happens in active directory domain controller setups.
