[Security] Bump rails from 5.1.5 to 5.2.2.1

[dependabot-preview]

Bumps rails from 5.1.5 to 5.2.2.1. 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: >= 5.1.0, <= 5.1.6.1

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: >= 5.1.0, <= 5.1.6.1

Broken Access Control vulnerability in Active Job
There is a vulnerability in Active Job. This vulnerability has been assigned the CVE identifier CVE-2018-16476.

Impact

Carefully crafted user input can cause Active Job to deserialize it using GlobalId and allow an attacker to have access to information that they should not have.

Vulnerable code will look something like this:

MyJob.perform_later(user_input)

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

Patched versions: >= 4.2.11, < 5.0.0; >= 5.0.7.1, < 5.1.0; >= 5.1.6.1, < 5.2.0; >= 5.2.1.1
Unaffected versions: < 4.2.0
