Detail

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.
