Ubuntu Security Notice USN-7042-2
October 09, 2024

cups-browsed vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 24.04 LTS

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.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 24.04 LTS
cups-browsed 2.0.0-0ubuntu10.2

In general, a standard system update will make all the necessary changes.
