    sudo vulnerability
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 19.04
    - Ubuntu 18.04 LTS
    - Ubuntu 16.04 LTS
    - Ubuntu 14.04 ESM
    - Ubuntu 12.04 ESM
    
    Summary:
    
    Sudo could be made to run commands as root if it called with
    a specially crafted user ID.
    
    Software Description:
    - sudo: Provide limited super user privileges to specific users
    
    Details:
    
    Joe Vennix discovered that Sudo incorrectly handled
    certain user IDs. An attacker could potentially exploit this
    to execute arbitrary commands as the root user.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 19.04:
      sudo                            1.8.27-1ubuntu1.1
      sudo-ldap                       1.8.27-1ubuntu1.1
    
    Ubuntu 18.04 LTS:
      sudo                            1.8.21p2-3ubuntu1.1
      sudo-ldap                       1.8.21p2-3ubuntu1.1
    
    Ubuntu 16.04 LTS:
      sudo                            1.8.16-0ubuntu1.8
      sudo-ldap                       1.8.16-0ubuntu1.8
    
    Ubuntu 14.04 ESM:
      sudo                            1.8.9p5-1ubuntu1.5+esm2
      sudo-ldap                       1.8.9p5-1ubuntu1.5+esm2
    
    Ubuntu 12.04 ESM:
      sudo                            1.8.3p1-1ubuntu3.8
      sudo-ldap                       1.8.3p1-1ubuntu3.8
    
    In general, a standard system update will make all the necessary changes.
