    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 18.04 LTS
    
    Summary:
    
    pip could be made to overwrite files as the administrator.
    
    Software Description:
    - python-pip: Python package installer
    
    Details:
    
    It was discovered that pip did not properly sanitize the filename during
    pip install. A remote attacker could possible use this issue to read and
    write arbitrary files on the host filesystem as root, resulting in a
    directory traversal attack. (CVE-2019-20916)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 18.04 LTS:
      python-pip                      9.0.1-2.3~ubuntu1.18.04.4
      python3-pip                     9.0.1-2.3~ubuntu1.18.04.4
    
    In general, a standard system update will make all the necessary changes.
