Package        : python-gnupg
Version        : 0.3.9-1+deb9u1
CVE ID         : CVE-2018-12020 CVE-2019-6690

A couple of vulnerabilites were found in python-gnupg, a Python
wrapper for the GNU Privacy Guard.


    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.


    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.

For Debian 9 stretch, these problems have been fixed in version

We recommend that you upgrade your python-gnupg packages.

For the detailed security status of python-gnupg please refer to
