+identified and fixed.  The vulnerability would allow unprivileged users to
+corrupt the result of @dfn{fixed-output derivations} such as source code
+tarballs and Git checkouts, which in turn could lead to local privilege
+escalation.
+
+This bug is fixed and Guix System users are advised to upgrade their system,
+with a command along the lines of:
+
+@example
+sudo guix system reconfigure /run/current-system/configuration.scm
+sudo herd restart guix-daemon
+@end example
+
+See @uref{https://issues.guix.gnu.org/69728} for more information on this
+issue.")

+qui peut ensuite permettre une élévation locale de privilèges.

+Ce problème est corrigé et les utilisateur·rices de Guix System sont invité·es
