Read Time:42 Second

USN-7043-1 fixed vulnerabilities in cups-filters. This update improves the
fix for CVE-2024-47176 by removing support for the legacy CUPS printer
discovery protocol entirely.

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. (CVE-2024-47176)
