[Security] Bump rails from 5.2.1.1 to 5.2.3

[dependabot-preview]

Bumps rails from 5.2.1.1 to 5.2.3. This update includes security fixes.

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:

Affected versions: >= 5.2.0, <= 5.2.2

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: >= 5.2.0, <= 5.2.2

Moderate severity vulnerability that affects railties

Possible Remote Code Execution Exploit in Rails Development Mode

Impact

With some knowledge of a target application it is possible for an attacker to
guess the automatically generated development mode secret token. This secret
token can be used in combination with other Rails internals to escalate to a
remote code execution exploit.

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

Releases

The 6.0.0.beta3 and 5.2.2.1 releases are available at the normal locations.

Workarounds

This issue can be mitigated by specifying a secret key in development mode.
In "config/environments/development.rb" add this:

Affected versions: >= 5.2.0, <= 5.2.2

Release notes

Sourced from rails's releases.

5.2.3

Active Support

• Add ActiveSupport::HashWithIndifferentAccess#assoc.

  assoc can now be called with either a string or a symbol.

  Stefan Schüßler

• Fix String#safe_constantize throwing a LoadError for incorrectly cased constant references.

  Keenan Brock

• Allow Range#=== and Range#cover? on Range

  Range#cover? can now accept a range argument like Range#include? and
  Range#===. Range#=== works correctly on Ruby 2.6. Range#include? is moved
  into a new file, with these two methods.

  utilum

• If the same block is included multiple times for a Concern, an exception is no longer raised.

  Mark J. Titorenko, Vlad Bokov

Active Model

• Fix date value when casting a multiparameter date hash to not convert
  from Gregorian date to Julian date.

  Before:

  Day.new({"day(1i)"=>"1", "day(2i)"=>"1", "day(3i)"=>"1"})
  => #<Day id: nil, day: "0001-01-03", created_at: nil, updated_at: nil>
  

  After:

  Day.new({"day(1i)"=>"1", "day(2i)"=>"1", "day(3i)"=>"1"})
  => #<Day id: nil, day: "0001-01-01", created_at: nil, updated_at: nil>
  

  Fixes #28521.

  Sayan Chakraborty

• Fix numericality equality validation of BigDecimal and Float
  by casting to BigDecimal on both ends of the validation.
