(title
(en "Risk of local privilege escalation @i{via} setuid programs"))
(body
(en "On Guix System, setuid programs were, until now, installed as
setuid-root @emph{and} setgid-root (in the @file{/run/setuid-programs}
directory). However, most of these programs are meant to run as setuid-root,
but not setgid-root. Thus, this setting posed a risk of local privilege
escalation.
This bug has been fixed and users are advised to upgrade their system, with a
command along the lines of:
@example
guix system reconfigure /run/current-system/configuration.scm
@end example
Users of Guix on a ``foreign distro'' are unaffected. See
@url{https://issues.guix.gnu.org/46395} for more information.")))
