Details
USN-7043-1 fixed a vulnerability in cups-filters. This update provides
the corresponding update for Ubuntu 16.04 LTS
Original advisory details:
Simone Margaritelli discovered that the cups-filters cups-browsed
component could be used to create arbitrary printers from outside
the local network. In combination with issues in other printing
components, a remote attacker could possibly use this issue to
connect to a system, created manipulated PPD files, and execute
arbitrary code when a printer is used. This update
disables support for the legacy CUPS printer discovery protocol.
