A vulnerability in the Guix build system

Description:
The Guix project has disclosed a security vulnerability in the build daemon 
that the distribution uses to build and install software locally. The 
vulnerability allows an existing unprivileged user to get access to a setuid 
binary, and from there potentially interfere with any other software built or 
installed on the computer. The project recommends upgrading the guix daemon 
now, to avoid the issue. This exploit requires the ability to start a 
derivation build and the
ability to run arbitrary code with access to the store in the root PID
namespace on the machine the build occurs on. As such, this represents
an increased risk primarily to multi-user systems and systems using
dedicated privilege-separation users for various daemons: without
special sandboxing measures, any process of theirs can take advantage
of this vulnerability.
