    Docker vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 19.04
    - Ubuntu 18.10
    - Ubuntu 18.04 LTS
    - Ubuntu 16.04 LTS
    
    Summary:
    
    Docker could be made to overwrite files as the administrator.
    
    Software Description:
    - docker.io: Linux container runtime
    
    Details:
    
    Aleksa Sarai discovered that Docker was vulnerable to a directory traversal
    attack. An attacker could use this vulnerability to read and write arbitrary
    files on the host filesystem as root.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 19.04:
      docker.io                       18.09.7-0ubuntu1~19.04.4
    
    Ubuntu 18.10:
      docker.io                       18.09.7-0ubuntu1~18.10.3
    
    Ubuntu 18.04 LTS:
      docker.io                       18.09.7-0ubuntu1~18.04.3
    
    Ubuntu 16.04 LTS:
      docker.io                       18.09.7-0ubuntu1~16.04.4
    
    This update uses a new upstream release, which includes additional bug
    fixes. In general, a standard system update will make all the necessary
    changes.
