Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS : APT vulnerability (USN-3863-1)

high Nessus Plugin ID 121328

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-3863-1 advisory.

 Max Justicz discovered that APT incorrectly handled certain parameters during redirects. If a remote attacker were able to perform a machine-in-the-middle attack, this flaw could potentially be used to install altered packages.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
