DSA-5547 pmix – security update

Debian Security Advisory

Francois Diakhate reported that a race condition in pmix, a library
implementing Process Management Interface (PMI) Exascale API, could
allow a malicious user to obtain ownership of an arbitrary file on the
filesystem when parts of the PMIx library are called by a process with
elevated privileges, resulting in privilege escalation. This may
happen under the default configuration of certain workload managers,
including Slurm.
