Summary
python-apt vulnerabilities
Details

USN-4247-1 fixed several vulnerabilities in python-apt. This update provides the corresponding updates for Ubuntu 12.04 ESM and Ubuntu 14.04 ESM.

Original advisory details:

It was discovered that python-apt would still use MD5 hashes to validate certain downloaded packages. If a remote attacker were able to perform a machine-in-the-middle attack, this flaw could potentially be used to install altered packages. (CVE-2019-15795)

It was discovered that python-apt could install packages from untrusted repositories, contrary to expectations. (CVE-2019-15796)
