passphrase property of the gnupg.GPG.encrypt() and gnupg.GPG.decrypt()

library passes --passphrase-fd=0 to the gpg executable, which expects the
passphrase on the first line of stdin, and the ciphertext to be decrypted
or plaintext to be encrypted on subsequent lines. By supplying a passphrase
containing a newline an attacker can control/modify the ciphertext/plaintext
being decrypted/encrypted (CVE-2019-6690).");
