Peter Korsgaard 493cedf3af samba4: security bump to version 4.5.7 
Fixes CVE-2017-2619:

   All versions of Samba prior to 4.6.1, 4.5.7, 4.4.11 are vulnerable to
   a malicious client using a symlink race to allow access to areas of
   the server file system not exported under the share definition.

   Samba uses the realpath() system call to ensure when a client requests
   access to a pathname that it is under the exported share path on the
   server file system.

   Clients that have write access to the exported part of the file system
   via SMB1 unix extensions or NFS to create symlinks can race the server
   by renaming a realpath() checked path and then creating a symlink. If
   the client wins the race it can cause the server to access the new
   symlink target after the exported share path check has been done. This
   new symlink target can point to anywhere on the server file system.

   This is a difficult race to win, but theoretically possible. Note that
   the proof of concept code supplied wins the race reliably only when
   the server is slowed down using the strace utility running on the
   server. Exploitation of this bug has not been seen in the wild.
