Ubuntu Security Notice 7042-3 - USN-7042-2 released an improved fix for cups-browsed. This update provides the corresponding update for Ubuntu 24.10. 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.
