Hide Forgot
Slurm's use of the 'xauth' command to manage X11 magic cookies can lead to an inadvertent disclosure of a user's cookie when setting up X11 forwarding on a node. An attacker monitoring /proc on the node could race the setup and steal the magic cookie, which may let them connect to that user's X11 session. A job would only be impacted if --x11 was requested at submission time.
