Debian Security Advisory

DSA-4371-1 apt -- security update

Date Reported:

22 Jan 2019

Affected Packages:

apt

Vulnerable:

Yes

Security database references:

In Mitre's CVE dictionary: CVE-2019-3462.

More information:

Max Justicz discovered a vulnerability in APT, the high level package manager. The code handling HTTP redirects in the HTTP transport method doesn't properly sanitize fields transmitted over the wire. This vulnerability could be used by an attacker located as a man-in-the-middle between APT and a mirror to inject malicous content in the HTTP connection. This content could then be recognized as a valid package by APT and used later for code execution with root privileges on the target machine.

Since the vulnerability is present in the package manager itself, it is recommended to disable redirects in order to prevent exploitation during this upgrade only, using:

apt -o Acquire::http::AllowRedirect=false update
apt -o Acquire::http::AllowRedirect=false upgrade

This is known to break some proxies when used against security.debian.org. If that happens, people can switch their security APT source to use:

deb http://cdn-fastly.deb.debian.org/debian-security stable/updates main

For the stable distribution (stretch), this problem has been fixed in version 1.4.9.

We recommend that you upgrade your apt packages.

Specific upgrade instructions:

If upgrading using APT without redirect is not possible in your situation, you can manually download the files (using wget/curl) for your architecture using the URL provided below, verifying that the hashes match. Then you can install them using dpkg -i.
