More information:

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

• CVE-2018-12020

  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-2019-6690

  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 0.3.9-1+deb9u1.

We recommend that you upgrade your python-gnupg packages.
