DESCRIPTION:
Canonical has acknowledged a vulnerability in Ubuntu, which can be
exploited by malicious people to bypass certain security features.

The vulnerability is caused due to the Ubuntu image shipped with Dell
Latitude 2110 systems being configured to allow package installations
without properly authenticating the package. This can be exploited to
e.g. execute arbitrary code with root privileges by modifying packages
via Man-in-the-Middle (MitM) attacks or by compromising an Ubuntu
archive mirror.

SOLUTION:
Apply updated packages.
