Action Text brings rich text content and editing to Rails. Starting in version 6.0.0 and prior to versions 6.1.7.9, 7.0.8.5, 7.1.4.1, and 7.2.1.1, there is a possible ReDoS vulnerability in the `plain_text_for_blockquote_node helper` in Action Text. Carefully crafted text can cause the `plain_text_for_blockquote_node` helper to take an unexpected amount of time, possibly resulting in a DoS vulnerability. All users running an affected release should either upgrade to versions 6.1.7.9, 7.0.8.5, 7.1.4.1, or 7.2.1.1 or apply the relevant patch immediately. As a workaround, users can avoid calling `plain_text_for_blockquote_node` or upgrade to Ruby 3.2. Ruby 3.2 has mitigations for this problem, so Rails applications using Ruby 3.2 or newer are unaffected. Rails 8.0.0.beta1 depends on Ruby 3.2 or greater so is unaffected.

The remote Debian 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-4383 advisory.

    rails a popular server side application framework was affected by multiple     vulnerabilities.

    CVE-2022-44566

        Given a value outside the range for a 64bit signed integer type         PostgreSQL will treat the column type as numeric. Comparing         integer values against numeric values can result in a slow         sequential scan.
        This behavior is configurable via         ActiveRecord::Base.raise_int_wider_than_64bit which         defaults to true.

    CVE-2023-28362

        The redirect_to method in Rails allows provided values         to contain characters which are not legal in an HTTP header         value. This results in the potential for downstream services         which enforce RFC compliance on HTTP response headers to remove         the assigned Location header.

    CVE-2023-38037

        ActiveSupport::EncryptedFile writes contents that will be         encrypted to a temporary file. The temporary file's permissions         are defaulted to the user's current `umask` settings, meaning         that it's possible for other users on the same system to read         the contents of the temporary file. Attackers that have access         to the file system could possibly read the contents of this         temporary file while a user is editing it

    CVE-2024-41128

        Action Pack is a framework for handling and responding         to web requests. There is a possible ReDoS vulnerability in         the query parameter filtering routines of Action Dispatch.
        Carefully crafted query parameters can cause query parameter         filtering to take an unexpected amount of time, possibly         resulting in a DoS vulnerability.

    CVE-2024-47887

        Action Pack is a framework for handling and responding         to web requests. There is a possible ReDoS vulnerability in         Action Controller's HTTP Token authentication.
        For applications using HTTP Token authentication via         `authenticate_or_request_with_http_token` or similar,         a carefully crafted header may cause header parsing         to take an unexpected amount of time, possibly resulting         in a DoS vulnerability

    CVE-2024-47888

        Action Text brings rich text content and editing to Rails.
        There is a possible ReDoS vulnerability in the         `plain_text_for_blockquote_node helper` in Action Text.
        Carefully crafted text can cause the `plain_text_for_blockquote_node`         helper to take an unexpected amount of time,         possibly resulting in a DoS vulnerability.

    CVE-2024-47889

        Action Mailer is a framework for designing email service layers.
        There is a possible ReDoS vulnerability in the block_format helper         in Action Mailer. Carefully crafted text can cause the block_format         helper to take an unexpected amount of time, possibly         resulting in a DoS vulnerability.

    CVE-2024-54133

        Action Pack is a framework for handling and responding         to web requests. There is a possible Cross Site Scripting (XSS)         vulnerability in the `content_security_policy` helper.
        Applications which set Content-Security-Policy (CSP) headers dynamically         from untrusted user input may be vulnerable to carefully crafted         inputs being able to inject new directives into the CSP.
        This could lead to a bypass of the CSP and its protection         against XSS and other attacks

    For Debian 11 bullseye, these problems have been fixed in version     2:6.0.3.7+dfsg-2+deb11u3.
