Readme

bash-shellshock Cookbook
=================

[![Build Status](https://travis-ci.org/chef-cookbooks/bash-shellshock.svg?branch=master)](http://travis-ci.org/chef-cookbooks/bash-shellshock)
[![Cookbook Version](https://img.shields.io/cookbook/v/bash-shellshock.svg)](https://supermarket.chef.io/cookbooks/bash-shellshock)

This cookbook is designed to test and optionally remediate the bash "shellshock" bug, more formally known as cve-2014-7169.

Once Chef-client has executed this recipe on one or more hosts, a list of all nodes that are vulnerable to the "Shellshock" exploit can be retrieved from the Chef server via `knife search:`

`knife search node 'bash:shellshock_vulnerable'`

Limitations
------------
This cookbook relies on the OS-native packaging system to provide patched versions of the bash package.

Requirements
------------
#### Platforms
* Tested on CentOS 6.5
* Tested on Ubuntu 12.04
* Should work on a wide variety of other systems

#### Chef
- Chef 11+

#### Cookbooks
* ohai (https://supermarket.chef.io/cookbooks/ohai)

Attributes
----------

* No user-configurable attributes

Recipes
-------

### bash-shellshock::default

* Audits and remediates Bash-CVE-2014-7169 ("Shellshock")

### bash-shellshock::audit

* Installs an OHAI plugin that will automatically audit nodes for the Shellshock vulnerability. This plugin creates two new values in OHAI:

  node['languages']['bash']['version'], a string. Returned from `bash --version`.
  node['languages']['bash']['shellshock_vulnerable'], a boolean. True if node is vulnerable.

### bash-shellshock::remediate

* If the node is marked vulnerable by the audit recipe, this recipe will attempt to upgrade bash via the native packaging system. Includes the audit recipe.
* Audits and remediates Bash-CVE-2014-7169 ("Shellshock")
