Ubuntu 18.04 LTS : apt vulnerability (USN-3746-1)

Medium Nessus Plugin ID 112032

Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

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.

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

Solution

Update the affected apt package.
