RHEL 9 : Satellite 6.18.7 Async Update (Important) (RHSA-2026:34368)

high Nessus Plugin ID 324596

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:34368 advisory.

Red Hat Satellite is a system management solution that allows organizations to configure and maintain their systems without the necessity to provide public Internet access to their servers or other client systems. It performs provisioning and configuration management of predefined standard operating environments.

Security Fix(es):

* foreman: Unauthorized modification of host configurations via broken access control (CVE-2026-5135)

* foreman: Privilege escalation to administrator-level access via usergroup role assignment manipulation (CVE-2026-5136)

* foreman: Information disclosure via improper validation of nested request parameters (CVE-2026-5138)

* foreman: Cross-tenant private SSH key disclosure via taxonomy scoping bypass (CVE-2026-5142)

* yggdrasil-worker-forwarder: Root.Chmod can follow symlinks out of the root (CVE-2026-32282)

* python-pillow: Pillow: Denial of Service via decompression bomb in FITS image processing (CVE-2026-40192)

Bug Fix(es):
* orphan cleanup triggers CapsuleContent::UpdateContentCounts regardless of automatic_content_count_updates setting (SAT-47204)

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

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

Solution

Update the affected packages.
