DESCRIPTION:
Ubuntu has issued an update for apt. This fixes a security issue,
which can be exploited by malicious people to conduct spoofing
attacks.

The security issue is caused due to the application incorrectly
verifying repositories with a pre-existing "InRelease" file and can
potentially be exploited to install altered packages via
Man-in-the-Middle (MitM) attacks.

SOLUTION:
Apply updated packages.
