    Package        : rails
    Version        : 2:6.0.3.7+dfsg-2+deb11u5
    CVE ID         : CVE-2022-32224
    Debian Bug     : 1016140

    A RCE (Remote Code Execution) escalation was discovered in Ruby on
    Rails, a MVC Ruby-based framework for web development.

    This vulnerability exists when using YAML-serialized columns in Active
    Record which could allow an attacker, who was able to manipulate data
    in the database (via means like SQL injection), the ability to
    escalate to an RCE.

    Common and safe YAML serialization is handled in this update (support
    for primary Ruby data types and Symbol, as well as newly-serialized
    HashWithIndifferentAccess objects).

    If your application serializes other classes as YAML, see the
    following page to reference these classes in
    config.active_record.yaml_column_permitted_classes, or disable
    protection entirely (not recommended, at your own risks) with
    config.active_record.use_yaml_unsafe_load=true.

    active-record/81017

    For Debian 11 bullseye, this problem has been fixed in version
    2:6.0.3.7+dfsg-2+deb11u5.

    We recommend that you upgrade your rails packages.

    For the detailed security status of rails please refer to
    its security tracker page at:
