Summary

cups-browsed could be made to run programs if it received specially crafted

network traffic.

Software Description:

- cups-browsed: OpenPrinting cups-browsed

Details:

USN-7042-1 fixed a vulnerability in cups-browsed. This update improves the

fix by removing support for the legacy CUPS printer discovery protocol

entirely.

Original advisory details:

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.
