Debian DLA-2074-1 : python-apt security update

medium Nessus Plugin ID 133219

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Several issues have been found in python-apt, a python interface to libapt-pkg.

CVE-2019-15795

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-2019-15796

It was discovered that python-apt could install packages from untrusted repositories, contrary to expectations.

For Debian 8 'Jessie', these problems have been fixed in version 0.9.3.13.

We recommend that you upgrade your python-apt packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
