"The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as
referenced in the RHSA-2026:34366 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):

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

      * dynflow-utils: Root.Chmod can follow symlinks out of the root (CVE-2026-32282)

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

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

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

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

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

      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.

      Bug Fix(es):

      * orphan cleanup triggers CapsuleContent::UpdateContentCounts regardless of
    automatic_content_count_updates setting (SAT-45923)

      * The custom repository fails to sync with the Capsule server, resulting in an error (SAT-44719)
