A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS
Summary:
cups-filters could be made to run programs if it received specially crafted
network traffic.
Software Description:
- cups-filters: OpenPrinting CUPS Filters
Details:
Simone Margaritelli discovered that the cups-filters cups-browsed component
could be used to create arbitrary printers from outside the local network.

PPD files, and execute arbitrary code when a printer is used. This update
disables support for the legacy CUPS printer discovery protocol.
