[Security] Bump actionpack from 4.1.4 to 4.1.16

[dependabot-preview]

Bumps actionpack from 4.1.4 to 4.1.16. 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

Sourced from The Ruby Advisory Database.

Arbitrary file existence disclosure in Action Pack Specially crafted requests can be used to determine whether a file exists on the filesystem that is outside the Rails application's root directory. The files will not be served, but attackers can determine whether or not the file exists.

Patched versions: ~> 3.2.20; ~> 4.0.11; ~> 4.1.7; >= 4.2.0.beta3 Unaffected versions: < 3.0.0

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:

Patched versions: >= 5.0.0.beta1.1; ~> 4.2.5, >= 4.2.5.1; ~> 4.1.14, >= 4.1.14.1; ~> 3.2.22.1 Unaffected versions: none

Arbitrary file existence disclosure in Action Pack Specially crafted requests can be used to determine whether a file exists on the filesystem that is outside the Rails application's root directory. The files will not be served, but attackers can determine whether or not the file exists. This vulnerability is very similar to CVE-2014-7818, but the specially crafted string is slightly different.

Patched versions: ~> 3.2.21; ~> 4.0.11.1; ~> 4.0.12; ~> 4.1.7.1; >= 4.1.8 Unaffected versions: < 3.0.0

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.

Patched versions: ~> 4.2.5, >= 4.2.5.1; ~> 4.1.14, >= 4.1.14.1 Unaffected versions: = 5.0.0.beta1

Sourced from The Ruby Advisory Database.

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.

Patched versions: >= 5.0.0.beta1.1; ~> 4.2.5, >= 4.2.5.1; ~> 4.1.14, >= 4.1.14.1; ~> 3.2.22.1 Unaffected versions: none
