    samba vulnerability
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 12.04 LTS
    
    Summary:
    
    Samba would allow unintended write access to files over the network.
    
    Software Description:
    - samba: SMB/CIFS file, print, and login server for Unix
    
    Details:
    
    It was discovered that Samba incorrectly handled CIFS share attributes when
    SMB2 was used. A remote authenticated user could possibly gain write access
    to certain shares, bypassing the intended permissions.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 12.04 LTS:
      samba                           2:3.6.3-2ubuntu2.6
    
    In general, a standard system update will make all the necessary changes.
