    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 14.04 ESM
    
    Summary:
    
    Several security issues were fixed in Samba.
    
    Software Description:
    - samba: SMB/CIFS file, print, and login server for Unix
    
    Details:
    
    USN-4217-1 fixed several vulnerabilities in Samba. This update provides
    the corresponding update for Ubuntu 14.04 ESM.
    
    Original advisory details:
    
     Andreas Oster discovered that the Samba DNS management server incorrectly
     handled certain records. An authenticated attacker could possibly use this
     issue to crash Samba, resulting in a denial of service. (CVE-2019-14861)
    
     Isaac Boukris discovered that Samba did not enforce the Kerberos
     DelegationNotAllowed feature restriction, contrary to expectations.
     (CVE-2019-14870)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 14.04 ESM:
      libsmbclient                    2:4.3.11+dfsg-0ubuntu0.14.04.20+esm4
      samba                           2:4.3.11+dfsg-0ubuntu0.14.04.20+esm4
    
    In general, a standard system update will make all the necessary changes.
