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

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

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 packages.
