    python-gnupg vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 19.04
    - Ubuntu 18.10
    - Ubuntu 18.04 LTS
    
    Summary:
    
    Several security issues were fixed in python-gnupg
    
    Software Description:
    - python-gnupg: Python wrapper for the GNU Privacy Guard 
    
    Details:
    
    Marcus Brinkmann discovered that GnuPG before 2.2.8 improperly handled certain
    command line parameters. A remote attacker could use this to spoof the output of
    GnuPG and cause unsigned e-mail to appear signed.
    (CVE-2018-12020)
    
    It was discovered that python-gnupg incorrectly handled the GPG passphrase. A
    remote attacker could send a specially crafted passphrase that would allow them
    to control the output of encryption and decryption operations.
    (CVE-2019-6690)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 19.04:
      python-gnupg                    0.4.3-1ubuntu1.19.04.1
      python3-gnupg                   0.4.3-1ubuntu1.19.04.1
    
    Ubuntu 18.10:
      python-gnupg                    0.4.1-1ubuntu1.18.10.1
      python3-gnupg                   0.4.1-1ubuntu1.18.10.1
    
    Ubuntu 18.04 LTS:
      python-gnupg                    0.4.1-1ubuntu1.18.04.1
      python3-gnupg                   0.4.1-1ubuntu1.18.04.1
    
    In general, a standard system update will make all the necessary changes.
