"The remote Redhat Enterprise Linux 8 / 9 host has packages installed that are affected by multiple vulnerabilities as
referenced in the RHSA-2023:4971 advisory.

    Red Hat Ansible Automation Platform provides an enterprise framework for building, deploying and managing
    IT automation at scale. IT Managers can provide top-down guidelines on how automation is applied to
    individual teams, while automation developers retain the freedom to write tasks that leverage existing
    knowledge without the overhead. Ansible Automation Platform makes it possible for users across an
    organization to share, vet, and manage automation content by means of a simple, powerful, and agentless
    language.

    Security Fix(es):
    * automation-controller: cryptography: memory corruption via immutable objects (CVE-2023-23931)
    * automation-controller: GitPython: Insecure non-multi options in clone and clone_from is not blocked
    (CVE-2023-40267)
    * python3-gitpython/python39-gitpython: Insecure non-multi options in clone and clone_from is not blocked
    (CVE-2023-40267)

    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.

    Additional changes:
    * ansible-core has been updated to 2.15.3 (AAP-15269)
    * automation-controller has been updated to 4.4.3 (AAP-15549)
    * python3-gitpython/python39-gitpython has been updated to 3.1.21 (AAP-15485)
    * automation controller: Fix bug that can cause a deadlock on shutdown when redis is unavailable.
    (AAP-14203)
    * automation controller: The login form no longer supports autocomplete on the password field due to
    security concerns. (AAP-15545)
