USN-7043-4

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)

Simone Margaritelli discovered that cups-filters incorrectly sanitized IPP data when creating PPD files. A remote attacker could possibly use this issue to manipulate PPD files and execute arbitrary code when a printer is used. (CVE-2024-47076)
