========================================================================== Ubuntu Security Notice USN-4247-2 January 22, 2020
python-apt regression ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 19.10 - Ubuntu 19.04 - Ubuntu 18.04 LTS - Ubuntu 16.04 LTS
Summary:
USN-4247-1 introduced a regression in python-apt.
Software Description: - python-apt: Python interface to libapt-pkg
Details:
USN-4247-1 fixed vulnerabilities in python-apt. The updated packages caused a regression when attempting to upgrade to a new Ubuntu release. This update fixes the problem.
We apologize for the inconvenience.
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 man-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)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 19.10: python-apt 1.9.0ubuntu1.3 python3-apt 1.9.0ubuntu1.3
Ubuntu 19.04: python-apt 1.8.5~ubuntu0.3 python3-apt 1.8.5~ubuntu0.3
Ubuntu 18.04 LTS: python-apt 1.6.5ubuntu0.2 python3-apt 1.6.5ubuntu0.2
Ubuntu 16.04 LTS: python-apt 1.1.0~beta1ubuntu0.16.04.8 python3-apt 1.1.0~beta1ubuntu0.16.04.8
In general, a standard system update will make all the necessary changes.
