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)
