RHEL 8 : environment-modules (RHSA-2026:82919)

high Nessus Plugin ID 365905

Synopsis

The remote Red Hat host is missing a security update for environment-modules.

Description

The remote Redhat Enterprise Linux 8 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2026:82919 advisory.

The environment-modules packages provide dynamic modification of user environment using module files. Each module file contains the information needed to configure the shell for an application. Once the package is initialized, the environment can be modified on a per-module basis using the module utility, which interprets module files.

Security Fix(es):

* environment-modules: Command injection in environment-modules Bash completion via malicious module names containing shell metacharacters (CVE-2026-85013)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux 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

Update the RHEL environment-modules package based on the guidance in RHSA-2026:82919.
