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 jessie/updates
main

For Debian 8 'Jessie', this problem has been fixed in version
1.0.9.8.5.

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.

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 the URL linked in the advisory."

your architecture using the URL provided in the advisory, verifying
that the hashes match. Then you can install them using dpkg -i."
