    Summary: python-gnupg vulnerabilities

    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)
