Description Michael Kaplan 2020-11-16 13:06:34 UTC
A review of Slurm's RPC handling code uncovered a potential buffer overflow with one utility function. The only affected use is in Slurm's PMIx MPI plugin, and a job would only be vulnerable if --mpi=pmix was requested, or the site has set MpiDefault=pmix in slurm.conf.
