    samba vulnerability
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 14.10
    - Ubuntu 14.04 LTS
    
    Summary:
    
    A security issue was fixed in Samba.
    
    Software Description:
    - samba: SMB/CIFS file, print, and login server for Unix
    
    Details:
    
    Andrew Bartlett discovered that Samba incorrectly handled delegation of
    authority when being used as an Active Directory Domain Controller. An
    attacker given delegation privileges could use this issue to escalate their
    privileges further.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 14.10:
      samba                           2:4.1.11+dfsg-1ubuntu2.1
    
    Ubuntu 14.04 LTS:
      samba                           2:4.1.6+dfsg-1ubuntu2.14.04.4
    
    In general, a standard system update will make all the necessary changes.
