Debian DSA-5547-1 : pmix - security update

high Nessus Plugin ID 184434

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

The remote Debian 11 / 12 host has packages installed that are affected by a vulnerability as referenced in the dsa-5547 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. For the oldstable distribution (bullseye), this problem has been fixed in version 4.0.0-4.1+deb11u1. For the stable distribution (bookworm), this problem has been fixed in version 4.2.2-1+deb12u1. We recommend that you upgrade your pmix packages. For the detailed security status of pmix please refer to its security tracker page at: https://security-tracker.debian.org/tracker/pmix

Tenable has extracted the preceding description block directly from the Debian security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the pmix packages.

For the stable distribution (bookworm), this problem has been fixed in version 4.2.2-1+deb12u1.
