Ruby Advisory Database

The Ruby advisory database seeks to compile all advisories relevant to Ruby libraries.

Goals

1. Provide advisory metadata in a simple yet structured YAML schema for automated tools to consume.
2. Avoid reinventing CVEs.
3. Avoid duplicating the efforts of OSVDB.

Directory Structure

The database is a list of directories that match the names of Ruby libraries on rubygems.org. Within each directory are one or more advisory files for the Ruby library. These advisory files are typically named using the advisories CVE identifier number.

gems/:
  rails/:
    2012-1098.yml  2012-2660.yml  2012-2661.yml  2012-3463.yml

If an advisory does not yet have a CVE, requesting a CVE is easy.

Format

Each advisory file contains the advisory information in YAML format:

---
gem: rails
cve: 2013-0156
url: http://osvdb.org/show/osvdb/89026
title: |
  Ruby on Rails params_parser.rb Action Pack Type Casting Parameter Parsing
  Remote Code Execution 

description: |
  Ruby on Rails contains a flaw in params_parser.rb of the Action Pack.
  The issue is triggered when a type casting error occurs during the parsing
  of parameters. This may allow a remote attacker to potentially execute
  arbitrary code.

cvss_v2: 10.0

patched_versions:
  - ~> 2.3.15
  - ~> 3.0.19
  - ~> 3.1.10
  - ">= 3.2.11"

Schema

• gem [String]: Name of the affected gem.
