[Security] Update rails requirement from ~> 4.1.4 to >= 4.1.4, < 6.2.0

[dependabot-preview]

Updates the requirements on rails to permit the latest version.

Vulnerabilities fixed

Sourced from The GitHub Security Advisory Database.

Critical severity vulnerability that affects actionview

Denial of Service Vulnerability in Action View

Impact

Specially crafted accept headers can cause the Action View template location code to consume 100% CPU, causing the server unable to process requests. This impacts all Rails applications that render views.

All users running an affected release should either upgrade or use one of the workarounds immediately.

Releases

The 6.0.0.beta3, 5.2.2.1, 5.1.6.2, 5.0.7.2, and 4.2.11.1 releases are available at the normal locations.

Workarounds

This vulnerability can be mitigated by wrapping render calls with respond_to blocks. For example, the following example is vulnerable:

High severity vulnerability that affects actionview

File Content Disclosure in Action View

Impact

There is a possible file content disclosure vulnerability in Action View. Specially crafted accept headers in combination with calls to render file: can cause arbitrary files on the target server to be rendered, disclosing the file contents.

The impact is limited to calls to render which render file contents without a specified accept format. Impacted code in a controller looks something like this:

class UserController < ApplicationController 
  def index 
    render file: "#{Rails.root}/some/file" 
  end 
end

Affected versions: >= 4.0.0, <= 4.2.11

Release notes

Sourced from rails's releases.

6.1.2

Active Support

• ActiveSupport::Cache::MemCacheStore now accepts an explicit nil for its addresses argument.

  config.cache_store = :mem_cache_store, nil
  is now equivalent to
  config.cache_store = :mem_cache_store
  and is also equivalent to
  config.cache_store = :mem_cache_store, ENV["MEMCACHE_SERVERS"] || "localhost:11211"
  which is the fallback behavior of Dalli

  This helps those migrating from :dalli_store, where an explicit nil was permitted.

  Michael Overmeyer

Active Model

• No changes.

Active Record

• Fix timestamp type for sqlite3.

  Eileen M. Uchitelle

• Make destroy async transactional.

  An active record rollback could occur while enqueuing a job. In this case the job would enqueue even though the database deletion rolledback putting things in a funky state.

  Now the jobs are only enqueued until after the db transaction has been committed.

  Cory Gwin

• Fix malformed packet error in MySQL statement for connection configuration.
