==========================================================================

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.

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
