[dependabot-preview]

Bumps actionpack from 4.2.5 to 4.2.11.1. This update includes security fixes.

Vulnerabilities fixed

Sourced from The Ruby Advisory Database.

Possible remote code execution vulnerability in Action Pack
There is a possible remote code execution vulnerability in Action Pack.
This vulnerability has been assigned the CVE identifier CVE-2016-2098.

Versions Affected: 3.2.x, 4.0.x, 4.1.x, 4.2.x
Not affected: 5.0+
Fixed Versions: 3.2.22.2, 4.1.14.2, 4.2.5.2

Impact

Applications that pass unverified user input to the render method in a
controller or a view may be vulnerable to a code injection.

Impacted code will look like this:

class TestController < ApplicationController
  def show
    render params[:id]
  end
end

Patched versions: \~> 3.2.22.2; \~> 4.2.5, >= 4.2.5.2; \~> 4.1.14, >= 4.1.14.2
Unaffected versions: >= 5.0.0.beta1

Timing attack vulnerability in basic authentication in Action Controller.
There is a timing attack vulnerability in the basic authentication support
in Action Controller. This vulnerability has been assigned the CVE
identifier CVE-2015-7576.

Versions Affected: All.
Not affected: None.
Fixed Versions: 5.0.0.beta1.1, 4.2.5.1, 4.1.14.1, 3.2.22.1

Impact

Due to the way that Action Controller compares user names and passwords in
basic authentication authorization code, it is possible for an attacker to
analyze the time taken by a response and intuit the password.

For example, this string comparison:

"foo" == "bar"

is possibly faster than this comparison:

Object leak vulnerability for wildcard controller routes in Action Pack
There is an object leak vulnerability for wildcard controllers in Action Pack.
This vulnerability has been assigned the CVE identifier CVE-2015-7581.

Versions Affected: >= 4.0.0 and < 5.0.0.beta1
Not affected: < 4.0.0, 5.0.0.beta1 and newer
Fixed Versions: 4.2.5.1, 4.1.14.1

Impact

Users that have a route that contains the string ":controller" are susceptible
to objects being leaked globally which can lead to unbounded memory growth.
To identify if your application is vulnerable, look for routes that contain
":controller".

Internally, Action Pack keeps a map of "url controller name" to "controller
class name". This map is cached globally, and is populated even if the
controller class doesn't actually exist.

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

Possible Object Leak and Denial of Service attack in Action Pack
There is a possible object leak which can lead to a denial of service
vulnerability in Action Pack. This vulnerability has been
assigned the CVE identifier CVE-2016-0751.

Versions Affected: All.
Not affected: None.
Fixed Versions: 5.0.0.beta1.1, 4.2.5.1, 4.1.14.1, 3.2.22.1

Impact

A carefully crafted accept header can cause a global cache of mime types to
grow indefinitely which can lead to a possible denial of service attack in
Action Pack.

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

Releases

The FIXED releases are available at the normal locations.
