Summary:	The remote host is missing an update for the 'lightdm' package(s) announced via the USN-3285-1 advisory.
Description:	Summary: The remote host is missing an update for the 'lightdm' package(s) announced via the USN-3285-1 advisory. Vulnerability Insight: Tyler Hicks discovered that LightDM did not confine the user session for guest users. An attacker with physical access could use this issue to access files and other resources that they should not be able to access. In the default installation, this includes files in the home directories of other users on the system. This update fixes the issue by disabling the guest session. It may be re-enabled in a future update. Please see the bug referenced below for instructions on how to manually re-enable the guest session. Affected Software/OS: 'lightdm' package(s) on Ubuntu 16.10, Ubuntu 17.04. Solution: Please install the updated package(s). CVSS Score: 2.1 CVSS Vector: AV:L/AC:L/Au:N/C:P/I:N/A:N
