DESCRIPTION:
Some vulnerabilities have been reported in Simple Linux Utility for
Resource Management (SLURM), which can be exploited by malicious,
local users to gain escalated privileges.

1) A vulnerability is caused due to an error within the sbcast
implementation when establishing supplemental groups, which can be
exploited to e.g. access files with the supplemental group privileges
of the slurmd daemon.

1) A vulnerability is caused due to the slurmctld daemon not properly
dropping supplemental groups when handling the "strigger" command,
which can be exploited to e.g. access files with the supplemental
group privileges of the slurmctld daemon.

The vulnerability is reported in all versions of 1.2 and 1.3 prior to
1.3.15.
