Releases
Packages
- 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.
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.
