[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:

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 

Affected versions: >= 4.0.0, <= 4.2.11

Release notes

Sourced from rails's releases.

6.1.0

Active Support

• Ensure MemoryStore disables compression by default. Reverts behavior of MemoryStore to its prior rails 5.1 behavior.

  Max Gurewitz

• Calling iso8601 on negative durations retains the negative sign on individual digits instead of prepending it.

  This change is required so we can interoperate with PostgreSQL, which prefers negative signs for each component.

  Compatibility with other iso8601 parsers which support leading negatives as well as negatives per component is still retained.

  Before:

  (-1.year - 1.day).iso8601
  # => "-P1Y1D"
  

  After:

  (-1.year - 1.day).iso8601
  # => "P-1Y-1D"
