USN-7042-1: cups-browsed vulnerability
26 September 2024

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

Releases
Ubuntu 24.04 LTS

Packages
cups-browsed - OpenPrinting cups-browsed

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
cups-browsed - 2.0.0-0ubuntu10.1
In general, a standard system update will make all the necessary changes.
