CVE-2024-48936

SchedMD Slurm before 24.05.4 has Incorrect Authorization. A mistake in authentication handling in stepmgr could permit an attacker to execute processes under other users' jobs. This is limited to jobs explicitly running with --stepmgr, or on systems that have globally enabled stepmgr via SlurmctldParameters=enable_stepmgr in their configuration.

These are all security issues fixed in the libnss_slurm2-24.05.4-1.1 package on the GA media of openSUSE Tumbleweed.

This update for slurm and pdsh fixes the following issues:

slurm was updated to version 24.11.1 using package slurm_24_11:

• Security issues fixed:

  • CVE-2024-48936: Fixed authentication handling in stepmgr that could permit an attacker to execute processes under other users' jobs (bsc#1236722)
  • CVE-2024-42511: Fixed vulnerability with switch plugins where a user could override the isolation between Slingshot VNIs or IMEX channels (bsc#1236726)

• Important remarks:

  • Slurm can be upgraded from version 23.02, 23.11 or 24.05 to version 24.11 without loss of jobs or other state information. Upgrading directly from an earlier version of Slurm will result in loss of state information.
  • If using the slurmdbd (Slurm DataBase Daemon) you must update this first.
  • The 24.11 slurmdbd will work with Slurm daemons of version 23.02 and above. You will not need to update all clusters at the same time, but it is very important to update slurmdbd first and having it running before updating any other clusters making use of it.
  • If using a backup DBD you must start the primary first to do any database conversion, the backup will not start until this has happened.
  • All SPANK plugins must be recompiled when upgrading from any Slurm version prior to 24.11.

• Highlights of changes:

  • Fixed issues related to the modified startup handling for slurmdbd: moved PID file to /run/slurmdbd (bsc#1236928)
  • Create slurm-owned log file on behalf of slurmdbd (bsc#1236929)
  • Added report AccountUtilizationByQOS to sreport.
  • AccountUtilizationByUser is able to be filtered by QOS.
  • Added autodetected gpus to the output of slurmd -C
  • Added ability to submit jobs with multiple QOS. These are sorted by priority highest being the first.
  • Removed the instant on feature from switch/hpe_slingshot.
  • slurmctld : Changed incoming RPC handling to dedicated thread pool with asynchronous handling of I/O that can be configured via conmgr_* entries under SlurmctldParameters in slurm.conf.

• Configuration File Changes (see appropriate man page for details)

  • Added SchedulerParameters=bf_allow_magnetic_slot option. It allows jobs in magnetic reservations to be planned by backfill scheduler.
  • Added TopologyParam=TopoMaxSizeUnroll=# to allow --nodes=<min>-<max> for topology/block.
  • Added DataParserParameters slurm.conf parameter to allow setting default value for CLI --json and --yaml arguments.
  • Hardware collectives in switch/hpe_slingshot now requires enable_stepmgr.
  • Added connection related parameters to slurm.conf under SlurmctldParameters:
    conmgr_max_connections: Defaults to 150 connections.
    conmgr_threads: Defaults to 64 threads for slurmctld.
    conmgr_use_poll: Defaults is to use epoll in Linux.
    conmgr_connect_timeout: Defaults to MessageTimeout.
    conmgr_read_timeout: Defaults to MessageTimeout.
    conmgr_wait_write_delay: Defaults to MessageTimeout.
    conmgr_write_timeout: Defaults to MessageTimeout.
  • Added SlurmctldParamters=ignore_constraint_validation to ignore constraint/feature validation at submission.
  • Added SchedulerParameters=bf_topopt_enable option to enable experimental hook to control backfill.

• Command Changes (see man pages for details):

  • Remove srun --cpu-bind=rank.
  • Add '%b' as a file name pattern for the array task id modulo 10.
  • sacct : Respect --noheader for --batch-script and --env-vars.
  • Add sacctmgr ping command to query status of slurmdbd.
  • sbcast : Add --nodelist option to specify where files are transmitted to
  • sbcast : Add --no-allocation option to transmit files to nodes outside of a job allocation.
  • slurmdbd : Add -u option. This is used to determine if restarting the DBD will result in database conversion.
  • Remove `salloc…
