There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - In mistune through 2.0.2, support of inline markup is implemented by using regular expressions that can
    involve a high amount of backtracking on certain edge cases. This behavior is commonly named catastrophic
    backtracking. (CVE-2022-34749)

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:2711 advisory.

    Red Hat Ceph Storage is a scalable, open, software-defined storage platform that combines the most stable     version of the Ceph storage system with a Ceph management platform, deployment utilities, and support     services.

    ==========================================     IMPORTANT:
    The Red Hat Ceph Storage team has migrated our defect tracking from Bugzilla to an internal Jira system.
    Bug fixes and CVE information that was previously listed in the errata releases are now listed in the     Release Notes.

    During the migration period, some defect details might still appear temporarily in the Errata. However,     the release notes contain the most current and authoritative information, including the complete list of     fixes and security updates.

    Refer to the release notes going forward for the latest and most accurate fix and CVE information.

The remote Fedora 37 host has packages installed that are affected by a vulnerability as referenced in the FEDORA-2022-e4f5866111 advisory.

    - updates `mistune` to 2.0.4
    - `m2r` updated to pin dependency to `mistune < 2`
    - new package: `python-mistune08` compatibility package, to be used by dependents that cannot use the new     mistune (namely `nbconvert`)
    - new package: `python-sphinx-typlog-theme`, needed to build `mistune` 2.x documentation

    ----

    Compatibility package for mistune 0.8, so we can update mistune to 2x without breaking unported dependents     like nbconvert
