    python-apt vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 14.04 ESM
    - Ubuntu 12.04 ESM
    
    Summary:
    
    Several security issues were fixed in python-apt.
    
    Software Description:
    - python-apt: Python interface to libapt-pkg
    
    Details:
    
    USN-4247-1 fixed several vulnerabilities in python-apt. This update
    provides the corresponding updates for Ubuntu 12.04 ESM and Ubuntu 14.04 ESM.
    
    Original advisory details:
    
     It was discovered that python-apt would still use MD5 hashes to validate
     certain downloaded packages. If a remote attacker were able to perform a
     man-in-the-middle attack, this flaw could potentially be used to install
     altered packages. (CVE-2019-15795)
    
     It was discovered that python-apt could install packages from untrusted
     repositories, contrary to expectations. (CVE-2019-15796)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 14.04 ESM:
      python-apt                      0.9.3.5ubuntu3+esm2
      python3-apt                     0.9.3.5ubuntu3+esm2
    
    Ubuntu 12.04 ESM:
      python-apt                      0.8.3ubuntu7.5
      python3-apt                     0.8.3ubuntu7.5
    
    In general, a standard system update will make all the necessary changes.
