    Ubuntu Security Notice USN-1423-1
    April 13, 2012
    
    samba vulnerability
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 11.10
    - Ubuntu 11.04
    - Ubuntu 10.04 LTS
    - Ubuntu 8.04 LTS
    
    Summary:
    
    Samba could be made to run programs as the administrator if it received
    specially crafted network traffic.
    
    Software Description:
    - samba: SMB/CIFS file, print, and login server for Unix
    
    Details:
    
    Brian Gorenc discovered that Samba incorrectly calculated array bounds when
    handling remote procedure calls (RPC) over the network. A remote,
    unauthenticated attacker could exploit this to execute arbitrary code as the
    root user. (CVE-2012-1182)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 11.10:
      samba                           2:3.5.11~dfsg-1ubuntu2.2
    
    Ubuntu 11.04:
      samba                           2:3.5.8~dfsg-1ubuntu2.4
    
    Ubuntu 10.04 LTS:
      samba                           2:3.4.7~dfsg-1ubuntu3.9
    
    Ubuntu 8.04 LTS:
      samba                           3.0.28a-1ubuntu4.18
    
    In general, a standard system update will make all the necessary changes.
