Description Patrick Del Bello 2022-05-05 18:11:51 UTC 
An architectural flaw with how credentials are handled can be exploited 
to allow an unprivileged user to impersonate the SlurmUser account. 
Access to the SlurmUser account can be used to execute arbitrary 
processes as root.

This issue impacts all Slurm releases since at least Slurm 1.0.0.

Systems remain vulnerable until all slurmdbd, slurmctld, and slurmd 
processes have been restarted in the cluster.

Once all daemons have been upgraded sites are encouraged to add 
"block_null_hash" to CommunicationParameters. That new option provides 
additional protection against a potential exploit.
