"The remote Redhat Enterprise Linux 9 host has packages installed that are affected by a vulnerability as referenced in
the RHSA-2026:39812 advisory.

    OpenStack Image Service (code-named Glance) provides
    discovery, registration, and delivery services for virtual disk images. The
    Image Service API server provides a standard REST interface for querying
    information about virtual disk images stored in a variety of back-end
    stores, including OpenStack Object Storage. Clients can register new
    virtual disk images with the Image Service, query for information on
    publicly available disk images, and use the Image Service's client library
    for streaming virtual disk images.

    Security Fix(es):

    * openstack-glance: OpenStack Glance  Unvalidated URI Fetch in OVF
    Processing (SSRF) ()

    * openstack-glance: OpenStack Glance  Redirect Validation Bypass in
    glance-download Import (SSRF) ()

    * OpenStack Glance: Server-Side Request Forgery leading to unauthorized
    internal network access (CVE-2026-34881)

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