Details

USN-7042-1 fixed a vulnerability in cups-browsed. This update improves the
fix by removing support for the legacy CUPS printer discovery protocol
entirely.

Original advisory details:

Simone Margaritelli discovered that cups-browsed 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.
