The remote Samba server, according to its version number, has 
a bug in the length checking for encrypted password change
requests from clients. A client could potentially send an encrypted
password, which, when decrypted with the old hashed password could be
used as a buffer overrun attack on the stack of smbd. 

Solution : upgrade to Samba 2.2.7
