Ubuntu Security Notice USN-3746-1
August 20, 2018

apt vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 18.04 LTS

Summary:

An attacker could trick APT into installing altered packages.

Software Description:
- apt: Advanced front-end for dpkg

Details:

It was discovered that APT incorrectly handled the mirror method
(mirror://). If a remote attacker were able to perform a man-in-the-middle
attack, this flaw could potentially be used to install altered packages in
environments configured to use mirror:// entries.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 18.04 LTS:
  apt                             1.6.3ubuntu0.1

In general, a standard system update will make all the necessary changes.
