"The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as
referenced in the RHSA-2022:1708 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):

    2023859 puppet: unsafe HTTP redirect (CVE-2021-27023)
    2023853 puppet: silent configuration failure in agent (CVE-2021-27025)

    This update fixes the following bugs:

    2070996 Upgrade to Satellite 6.10 fails at db:migrate stage if there are errata reference present for some
    ostree\puppet type repos
    2070991 Warning: postgresql.service changed on disk, when calling foreman-maintain service restart

    2070994 Index content is creating duplicated errata in katello_erratum table after upgrading to Satellite
    6.10
    2070999 Fail to import contents when the connected and disconnected Satellite have different product
    labels for the same product
    2071002 Error when importing content and same package belongs to multiple repositories
    2071006 Content not accessible after importing
