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

Affected versions: >= 4.0.0, <= 4.2.11

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 

... (truncated)

Affected versions: >= 4.0.0, <= 4.2.11

Sourced from The Ruby Advisory Database.

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, = 5.2.1.1 Unaffected versions: < 4.2.0
