USN-3746-1: APT vulnerability

20 August 2018

An attacker could trick APT into installing altered packages.



  • apt - Advanced front-end for dpkg


It was discovered that APT incorrectly handled the mirror method
(mirror://). If a remote attacker were able to perform a machine-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

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